Overview

What this migration involves

Moving from GanttPRO to Microsoft Project is a migration from a web-based collaborative Gantt chart tool to a desktop and cloud scheduling engine built for complex project structures. GanttPRO organizes work as Projects containing Summary Tasks, Tasks, and Subtasks in a nested hierarchy; Microsoft Project uses Tasks with Outline Level and Summary fields to reconstruct that hierarchy. The most technically significant migration challenge is the virtual resource model: GanttPRO distinguishes project members from role-based virtual resources with assigned cost rates, and converting virtual resources to actual resource assignments in Microsoft Project requires a manual cost-rate reconciliation step. We also handle GanttPRO's API constraints (Public Beta, 5 req/sec rate limit, Business tier requirement) by combining UI-based XLSX export for data extraction with Microsoft Project's native MPP import capability. Saved filters, custom templates, and portfolio views do not migrate as configuration; we deliver written inventories for the customer's admin to rebuild in Microsoft Project. Time logs and budget data migrate as custom fields or assignment notes where the destination schema supports them.

Why teams make this switch

Two sides of the same decision

Leaving

GanttPRO logo

GanttPRO

What's pushing teams away

  • G2 reviews cite expensive pricing as a top frustration, with multiple mentions that the cost poses challenges for students and small businesses operating on limited budgets.
  • Users report a steep learning curve that makes navigation difficult for beginners, particularly when moving from simpler tools like spreadsheet-based planning.
  • Limited customization options restrict flexibility, with users noting that advanced features feel constrained compared to competing project management tools.
  • Reviews mention missing project duplication functionality and insufficient reporting modules as gaps that drive users to look for alternatives.
  • The platform lacks a QuickBooks integration, which frustrates teams whose invoicing depends on direct time-tracking connections.

Choosing

Microsoft Project logo

Microsoft Project

What's pulling them in

  • Organizations already running Microsoft 365 and Azure AD adopt Microsoft PPM because it slots into existing identity, Teams, and SharePoint infrastructure without requiring a separate identity provider or SSO vendor.
  • Enterprise PMOs choose it for critical-path scheduling, baseline comparison, cross-project dependencies, and resource utilization reporting that standalone PM tools cannot replicate at this depth.
  • Project Online's integration with Power BI gives portfolio-level dashboards and cost-rollup reporting that satisfies executive governance requirements without third-party BI tooling.
  • Government, financial services, and healthcare organizations select it because FedRAMP, ISO 27001, and SOC 2 compliance certifications meet enterprise procurement requirements out of the box.
  • Large IT departments default to it as the market-leader in project portfolio management software, often driven by corporate licensing agreements that bundle it with other Microsoft 365 seats.

Object mapping

How GanttPRO objects map to Microsoft Project

Each row shows how a GanttPRO object lands in Microsoft Project, including any object-level transformations, lookup resolution, or schema-design dependencies.

Typical mapping — final map is confirmed during the sample migration step.

GanttPRO

Project

maps to

Microsoft Project

Project

1:1
Fully supported

GanttPRO Projects map directly to Microsoft Project files (MPP) or Project Online/Project for the Web projects. We preserve project name, description, start date, and the auto-scheduling toggle. GanttPRO's duration step (hours/days/weeks/months) maps to Microsoft Project's calendar and task mode settings. The project-level working day configuration maps to Microsoft Project's calendar (Project Calendar in desktop, Working Days in Project Online). Multi-project migrations in GanttPRO are handled as individual MPP files or as separate projects in the destination Project Online site.

GanttPRO

Summary Task

maps to

Microsoft Project

Task (Summary)

1:1
Fully supported

GanttPRO Summary Tasks map to Microsoft Project Tasks with the Summary flag set to Yes. The parent-child hierarchy is reconstructed using Outline Level and WBS code fields in Microsoft Project. We preserve the summary task name, start and end dates (rolled up from subtasks), and the Summary checkbox. When subtasks are indented under a summary task in GanttPRO, we generate the matching indentation structure in Microsoft Project's task hierarchy.

GanttPRO

Task

maps to

Microsoft Project

Task

1:1
Fully supported

Standard GanttPRO Tasks map directly to Microsoft Project Tasks with all standard fields preserved: Task Name, Start, Finish, Duration, Duration Type (elapsed/actual), Priority, Status, and the Notes/Description field. Task color coding from GanttPRO maps to Microsoft Project's Text 1-8 or Flag fields, which can be used for visual categorization in the destination. Task-level percent complete and physical percent complete migrate to the corresponding Microsoft Project fields.

GanttPRO

Subtask

maps to

Microsoft Project

Task (child)

1:1
Fully supported

GanttPRO Subtasks map to Microsoft Project Tasks nested under their parent Summary Task. We preserve subtask-level dates, assignees, and any custom field values. Subtask numbering from GanttPRO (which reviewers on Capterra cite as a standout feature) does not have a direct Microsoft Project equivalent; we generate WBS codes that replicate the numbering structure during migration. Flattening subtask hierarchies is not required because Microsoft Project supports the same parent-child nesting model as GanttPRO.

GanttPRO

Dependency

maps to

Microsoft Project

Predecessor Link

1:1
Fully supported

All four GanttPRO dependency types (Finish-to-Start, Start-to-Start, Finish-to-Finish, Start-to-Finish) map directly to Microsoft Project predecessor types. GanttPRO uses the successor task bar or task settings to define dependency types; Microsoft Project uses the Predecessors field with type codes (FF, FS, SF, SS). We translate each dependency, flag any circular reference detected during import, and preserve lag time and lead time values as offset days in the predecessor string. The orange arrow visualization from GanttPRO does not migrate; it is a GanttPRO UI rendering artifact.

GanttPRO

Resource (project member)

maps to

Microsoft Project

Resource (work)

1:1
Fully supported

GanttPRO project members (human users assigned to tasks) map to Microsoft Project Work Resources. We map the member name, email (for cross-reference), and the Max Units value. GanttPRO's resource workload percentages map to Microsoft Project's resource assignment units. Where GanttPRO assigns a cost rate to a project member, we map that to the resource's Standard Rate in Microsoft Project. Resource calendars in Microsoft Project (working time exceptions per resource) can be populated from GanttPRO working day settings if those are resource-specific.

GanttPRO

Virtual Resource

maps to

Microsoft Project

Resource (work) + custom field

lossy
Fully supported

GanttPRO virtual resources are role-based placeholders with assigned cost rates but no associated user account. Microsoft Project does not have a virtual resource concept; all resources are actual. We convert virtual resources to Microsoft Project Work Resources using the virtual resource's name, role description, and cost rate. We flag virtual resource conversions in the migration report because cost calculations in Microsoft Project depend on the Standard Rate and accrue against the project budget differently than in GanttPRO's automatic budget mode. The customer's admin should review budget totals after migration for any variance introduced by the conversion.

GanttPRO

Custom Field

maps to

Microsoft Project

Custom Field

1:1
Fully supported

GanttPRO custom fields (available on Advanced tier+) are available in nine types: Text, Number, Date, List, Checkbox, Color, Multiselect, People, and Label. Microsoft Project custom fields support a narrower set of types. We map Text to Text, Number to Number, Date to Date, Checkbox to Flag, and List to Text (since Microsoft Project does not have a dropdown custom field equivalent at core; Enterprise tier or Project Online with Project Client is required for enterprise custom fields). Color, Multiselect, People, and Label types from GanttPRO are mapped to Text or Flag fields with the original value preserved as a string. We flag field types that cannot map directly so the customer can decide whether to accept text representation or restructure the field in Microsoft Project.

GanttPRO

Portfolio

maps to

Microsoft Project

Project Site or Power BI

1:1
Fully supported

GanttPRO Portfolios group multiple projects for high-level monitoring. Microsoft Project has no native portfolio object in the desktop application or Project for the Web at the base tier. We extract portfolio membership (which projects belong to which portfolio) and deliver it as a written reference list. For organizations with Project Online Plan 5 or Project Server, the portfolio view can be reconstructed using the Project Web App portfolio dashboards. For Project for the Web, Power BI or a SharePoint site structure can replicate the portfolio monitoring view.

GanttPRO

Time Log

maps to

Microsoft Project

Assignment or custom field

1:1
Fully supported

GanttPRO Time Logs record hours worked against tasks with date, user, and optional comment. Microsoft Project does not have a native time-tracking object in the desktop application; timesheets require Project Server or Project Online with timesheet functionality enabled. We map time log entries to task assignment notes (as text: 'Time logged: X hours on Y date') or to a custom Timesheet Hours field on the task if the destination is Project Online with a timesheet-enabled site. Note that GanttPRO time log export is only available in XLSX format, so we convert the XLSX export to structured records during the extraction phase. Planned work hours from task assignments are preserved separately from logged time.

GanttPRO

Budget Data

maps to

Microsoft Project

Cost fields on task or project

1:1
Mapping required

GanttPRO supports automatic budget calculation (derived from resource rates and estimated hours) and manual budget entry. Where GanttPRO uses automatic mode, we extract both the calculated budget value and the underlying resource rate and hours data. In Microsoft Project, budget tracking requires the Project Summary Task with a Budget Cost field (available in Project Professional or Project Online with Project Plan 3+). We map GanttPRO's project-level budget to the Microsoft Project Budget Cost field, and task-level costs to assignment cost fields. Virtual resource costs migrate with the resource conversion as described above.

GanttPRO

Filter

maps to

Microsoft Project

View

lossy
Fully supported

GanttPRO saved filters (available on Advanced tier+) define task views by name, type, assignee, status, priority, date range, color, and custom fields. Microsoft Project Views store column, grouping, and filter configurations per project. We extract the filter definitions and deliver them as a written view specification document with the column order, sort order, grouping, and filter criteria for each saved filter. The customer's admin rebuilds the views in Microsoft Project using the View Definition dialog. Note that GanttPRO's Board View has no Microsoft Project equivalent; we note this in the gap analysis.

Pair-specific challenges

  • GanttPRO API is Public Beta with no SLA and 5 req/sec rate limit

    GanttPRO's REST API is explicitly in Public Beta with no documented SLA and no production readiness guarantee. The API enforces a 5 requests per second limit on insert, update, and delete operations. For a project with 400 tasks and dependencies, this alone creates over 80 seconds of API wait time before accounting for network latency. We handle this by using GanttPRO's UI-based XLSX export as the primary data extraction path for most migrations, and implementing retry logic with exponential backoff if API extraction is required for delta updates. Large migrations should not rely solely on the API. The API is also only available on Business and Enterprise tiers, so customers on Core or Advanced tiers cannot use API-based extraction without upgrading first.

  • Microsoft Project has no native multi-select or list custom field type

    GanttPRO supports nine custom field types including List, Multiselect, and Label, which allow multiple predefined values per task. Microsoft Project desktop and Project for the Web at base tiers do not have equivalent multi-select or dropdown custom field types. We map these to Text fields with the values concatenated as a comma-separated string. If the customer requires a true dropdown in Microsoft Project, they need Project Online with the Project Client and organizational custom fields enabled, or they accept text-based representation. We flag every multi-value custom field in the migration inventory so the customer can decide on acceptable data representation before migration begins.

  • Virtual resource cost rates require manual budget reconciliation

    GanttPRO virtual resources are role placeholders (e.g., 'Senior Developer', 'QA Engineer') with cost rates but no associated user account. When converted to Microsoft Project Work Resources, the cost rates map to Standard Rate on the resource, but the budget calculation model differs. GanttPRO's automatic budget mode derives costs from resource rates times estimated hours per task assignment. Microsoft Project calculates cost from the resource rate times the assignment actual work. We extract both the GanttPRO calculated budget and the underlying rates and hours, then map to Microsoft Project assignment cost fields. Budget totals should be reconciled by the customer's PM after migration because the calculation engine assumptions differ between platforms.

  • GanttPRO time log export is XLSX only and defaults to current month

    GanttPRO time logs export only to Excel format; there is no CSV, JSON, or direct API export. The default time log view in GanttPRO shows only the current month, which can silently exclude historical time entries if migration scoping does not explicitly request a full date range. We explicitly request the full date range during scoping and convert the XLSX time log to structured records for import into Microsoft Project. If the destination is Microsoft Project desktop without timesheet functionality, time log data migrates as task notes or a custom Timesheet Hours field. If the destination is Project Online with a timesheet-enabled site, the time log converts to timesheet entries against the matching resource assignments.

  • GanttPRO Board View and Portfolio view have no direct Microsoft Project equivalent

    GanttPRO's Board View displays tasks as Kanban cards organized by status or assignee, and the Portfolio view groups multiple projects for high-level monitoring. Microsoft Project (desktop and base Project for the Web) has no Board View or native Portfolio object. Board View tasks can be viewed as grouped task sheets in Microsoft Project but lose the card-based visual workflow. Portfolio membership is extracted as a reference list and can be reconstructed in Project Online Plan 5 via the portfolio dashboards, or in Power BI using project-level data exported from Microsoft Project. We document both gaps in the migration inventory for the customer to address post-migration.

Migration approach

Six steps for a successful GanttPRO to Microsoft Project data migration

  1. Discovery and plan assessment

    We audit the source GanttPRO account across tier (Core/Advanced/Business/Enterprise), project count, task count per project, custom field definitions, virtual resource usage, portfolio membership, time log date range, and saved filter configurations. We also assess the destination: Microsoft Project desktop (MPP files with Standard or Professional 2024), Project for the Web (cloud with Project Plan 3 or Plan 5), or Project Online (SharePoint-backed with Project Server capabilities). The discovery output is a written migration scope that identifies which GanttPRO tier features are in use, which require upgrade to Business tier for API access, and which destination product the customer has licensed.

  2. Data extraction via XLSX export

    We extract project data from GanttPRO using the UI-based XLSX export for primary data extraction, supplemented by API calls (where Business or Enterprise tier is available) for delta records modified after the export snapshot. The XLSX export covers tasks, dependencies, resources, and custom field values per project. Time logs are extracted separately with an explicitly requested full-date-range export to avoid the default current-month filter. Virtual resource definitions (name, role, cost rate) are extracted from the resource management section. We validate record counts against the GanttPRO UI before proceeding to transformation.

  3. Schema mapping and virtual resource reconciliation

    We design the mapping between GanttPRO and Microsoft Project objects: task hierarchy to outline level, dependencies to predecessor links with type codes, project members to work resources, and virtual resources to work resources with cost rates. Custom fields are mapped to their Microsoft Project equivalents with type translation for List, Multiselect, People, and Label fields (flagged as text-based). We generate a virtual resource conversion report so the customer's PM can review which role placeholders became actual resources and verify cost rate accuracy. Any GanttPRO custom field that cannot map directly is flagged with a recommended alternative field type or post-migration restructuring approach.

  4. Test migration to destination environment

    We run a full test migration into a validation environment: an MPP file for desktop destinations, or a Project Online site collection for cloud destinations. The customer's project manager reviews 25-50 tasks per project, spot-checks dependency chains, verifies virtual resource conversion, and confirms custom field values are readable in the destination. We validate that GanttPRO's critical path highlighting corresponds to the Longest Path in Microsoft Project and that any baseline data from GanttPRO maps to the Baseline fields in Microsoft Project. Any mapping corrections are applied before production migration. Filters and views are documented in this phase for the rebuild inventory.

  5. Production migration and cutover

    We run the production migration into the destination environment (MPP files or Project Online) in dependency order: project calendar and working days first, then resources (with virtual resource conversion applied), then tasks and subtasks in hierarchy order, then dependencies as predecessor links. Custom fields are populated per task after the core task data is in place. Time logs migrate as task notes or custom fields per the agreed mapping. We freeze GanttPRO writes during the cutover window, extract any delta records modified since the test migration snapshot, and apply them to the destination. The customer receives a reconciliation report comparing record counts and spot-checking field values in the destination against the GanttPRO source.

  6. Filter and view rebuild handoff

    We deliver a written inventory of every GanttPRO saved filter and custom view with its column order, sort order, grouping, and filter criteria translated to Microsoft Project View Definition language. The customer's admin rebuilds views in Microsoft Project using the View Definition dialog. We do not rebuild views as code inside the migration scope. We support a one-week hypercare window to resolve any data issues raised during the first week of use in Microsoft Project. We do not provide post-migration training, workflow design, or earned value reporting configuration; these are separate engagements.

Platform deep dives

Context on both ends of the pair

GanttPRO

Source

Strengths

  • Visual Gantt chart interface with clear timeline, dependency arrows, and critical path highlighting
  • Portfolio-level view for monitoring multiple projects simultaneously across an organization
  • Resource workload visualization with allocation tracking per resource or project
  • Template library covering construction, IT, marketing, and professional services industries
  • Auto-scheduling that recalculates dependent task dates when upstream changes occur

Weaknesses

  • API remains in Public Beta with no formal SLA, creating reliability risk for automated migrations
  • Strict 5 req/sec rate limit on insert/update/delete calls significantly extends bulk migration timelines
  • Business tier or higher required for API access, adding cost for teams currently on lower plans
  • Monthly subscriptions only available for teams of 5+ users, limiting adoption for smaller groups
  • Export permissions restricted to Account Owner, Admins, and Enterprise users with custom roles

Microsoft Project

Destination

Strengths

  • Deep critical-path scheduling with baseline comparison and cross-project dependency tracking unmatched by lighter PM tools.
  • Native Azure AD authentication, Teams integration, and Power BI reporting sit on infrastructure enterprises already license and manage.
  • Enterprise governance controls including demand intake workflows, resource request approval, and portfolio-level capacity analysis.
  • Supports both Waterfall and Agile methodologies within the same project, accommodating hybrid delivery teams.
  • Scalable from Project Plan 1 for small teams to Project Server on-premises for regulated industries with strict data-sovereignty requirements.

Weaknesses

  • Ease-of-use scores trail the category average by a wide margin; onboarding friction frustrates new users consistently across G2 and Capterra reviews.
  • Pricing ranks 42nd of 49 tools in its category — the total cost of ownership including IT administration and training is rarely recovered for small or mid-market teams.
  • No built-in client portal, external stakeholder sharing, or proofing workflow, limiting use cases to internal PMO environments only.
  • The web interface (Project for the web / Planner Premium) has materially weaker constraint controls and resource auto-leveling than the Windows desktop client.
  • Project for the web is being consolidated into Microsoft Planner, creating uncertainty about which product tier will host project portfolio data long-term.

Small migrations under 10 projects and 2,000 tasks land between two and four weeks. Medium migrations with 20-50 projects, complex dependency chains, virtual resource conversion, and budget data move to five to nine weeks. The timeline extends when the destination is Project Online rather than desktop MPP because of SharePoint site provisioning, Project Online permission configuration, and any cross-project portfolio reconstruction that requires Project Plan 5. We also recommend a one-week validation buffer between test and production migration so the customer's PM can review a full task sample in the destination before cutover.
