Overview

What this migration involves

Moving from Celoxis to Microsoft Project is a reverse-direction migration that requires careful handling of Celoxis data that has no direct Microsoft Project equivalent. Celoxis bundles financial tracking (timesheets, expenses, costing, billing), risk management, and portfolio dashboards as paid add-ons or native features; Microsoft Project centers on scheduling, Gantt charting, and resource leveling with financial modules available separately through Project Online or third-party integrations. We extract Celoxis project plans, task hierarchies, resource assignments, baselines, and custom fields via the Celoxis API, map them to Microsoft Project fields, and deliver a written inventory of Celoxis-only constructs — Custom Apps, Risk records, Issue workflows, and expense approvals — that cannot be recreated in Microsoft Project without manual rebuild or a Power Platform extension. We do not migrate Celoxis automations, approval chains, or reporting dashboards as code; these require admin rebuild in Microsoft Project or Power BI post-migration.

Why teams make this switch

Two sides of the same decision

Leaving

Celoxis logo

Celoxis

What's pushing teams away

  • New users find Celoxis difficult to learn — the depth of features creates a steep onboarding curve that frustrates smaller teams or less experienced PMs.
  • The user interface is widely described as dated, and the platform lacks a native mobile app, limiting usability for field or remote teams that need mobile access.
  • Feature richness becomes a drawback for simpler projects — teams using Celoxis for basic task management feel they are paying for capabilities they never use.
  • The pricing model charges extra for what many competitors bundle: Risk Management, Timesheet, Expense, and Billing are paid add-ons at +$5/user/month on top of the base tier.
  • Support quality is tiered — lower plans receive community-only support, which frustrates customers expecting consistent service across all tiers.

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 Celoxis objects map to Microsoft Project

Each row shows how a Celoxis 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.

Celoxis

Project

maps to

Microsoft Project

Project

1:1
Fully supported

Celoxis Projects map directly to Microsoft Project project files or Project Online projects. We extract the project name, status, start date, finish date, calendar, billing type (Fixed Price vs Hourly), and budget amounts. Celoxis workspace isolation (Data Isolation feature on Enterprise) does not map to a Microsoft Project concept — we flag multi-workspace customers and advise organizing projects into Microsoft Project site collections or Project Online project spaces post-migration.

Celoxis

Task and Subtask

maps to

Microsoft Project

Task

1:1
Fully supported

Celoxis Tasks and Subtasks map to Microsoft Project Task rows. We preserve parent-child hierarchy (outline level), WBS codes, task notes, and Celoxis custom fields defined on tasks. Celoxis split tasks map to Microsoft Project split tasks; recurring tasks map as individual tasks with a note field indicating the recurrence pattern since Microsoft Project does not store recurrence as a native recurring schedule.

Celoxis

Task Dependency

maps to

Microsoft Project

Task Dependency (Predecessor/Successor)

1:1
Fully supported

Celoxis task dependencies (finish-to-start, start-to-start, finish-to-finish, start-to-finish with lead/lag time) map directly to Microsoft Project predecessor links on the successor task. We reconstruct the full dependency graph and assign the correct predecessor type and lag days per Microsoft Project's predecessor field format (e.g., 'FS+2d' for finish-to-start with two-day lag).

Celoxis

Baseline

maps to

Microsoft Project

Baseline

1:1
Fully supported

Celoxis multiple baselines per project map to Microsoft Project's 11 available baseline slots (Baseline through Baseline 10). We assign Celoxis baseline snapshots to Microsoft Project baseline slots in chronological order. Baseline start dates, finish dates, durations, and costs migrate to the corresponding baseline fields.

Celoxis

Milestone

maps to

Microsoft Project

Milestone

1:1
Fully supported

Celoxis milestones with milestone type designation map to Microsoft Project milestone tasks (zero-duration tasks). We preserve the milestone name, date, and any associated milestone-level custom fields.

Celoxis

Resource (User)

maps to

Microsoft Project

Resource

1:1
Fully supported

Celoxis Resources (users and role-based resources) map to Microsoft Project Resources. We extract the resource name, type (Material vs Work), Max Units, Cost Rate Table entries (per-hour cost), and billing rate from Celoxis. Note that Microsoft Project does not have a separate billing rate field — cost rate is the internal rate only. Any Celoxis billing rate used for client invoicing must be recorded as a custom field in Microsoft Project.

Celoxis

Resource Assignment

maps to

Microsoft Project

Assignment (Task-Resource pairing)

1:1
Fully supported

Celoxis resource-task assignments map to Microsoft Project Assignments with the assigned resource, units (percentage or hours), and work. We preserve assignment-level notes, overtime settings, and the Celoxis booking type (Committed vs Proposed) as a custom field on the assignment.

Celoxis

Custom Fields

maps to

Microsoft Project

Custom Fields

lossy
Mapping required

Celoxis custom fields (25–1000 depending on tier) defined on Projects, Tasks, and Resources map to Microsoft Project custom fields of the closest matching type: Text, Number, Date, Flag, or Outline Code. We export the field definition (name, type, picklist options) and map values during the data phase. Microsoft Project custom fields have a 64-character name limit and no concept of workspace-scoped custom fields — all custom fields are project-level in desktop MS Project and org-level in Project Online.

Celoxis

Risk

maps to

Microsoft Project

No equivalent standard object

1:1
Fully supported

Celoxis Risk records (available on Professional and above or as a paid add-on) have severity, probability, mitigation, owner, and status fields. Microsoft Project has no native Risk register object. We export the Risk records as a CSV with all fields and deliver them as a structured handoff document. The customer can recreate risks in a SharePoint list, Power Apps canvas app, or a third-party risk management tool. Risk Management is a paid Celoxis add-on at $5/user/month — we verify the source account has this module active at scoping.

Celoxis

Issue

maps to

Microsoft Project

No equivalent standard object

1:1
Fully supported

Celoxis Issues have their own workflow states, assignee, priority, and linked project context. Microsoft Project has no native Issue tracker. We export Issue records as a CSV. The customer recreates issue tracking in SharePoint, Microsoft Lists, or a dedicated service desk tool. The Issue approval workflow state is not exportable and must be re-established in the replacement tool.

Celoxis

Timesheet

maps to

Microsoft Project

No equivalent standard object

1:1
Fully supported

Celoxis Timesheet entries (billable and non-billable time entries with activity codes and approval status) have no Microsoft Project equivalent. Microsoft Project tracks work assignments but does not include a timesheet submission and approval module. We export timesheet records as CSV. The customer can move timesheet data to Microsoft Dynamics 365 Project Operations, Smartsheet, or another PSA tool if timesheet tracking continues post-migration. Timesheet module is a paid add-on on Celoxis Essential; we verify its active status at scoping.

Celoxis

Expense

maps to

Microsoft Project

No equivalent standard object

1:1
Fully supported

Celoxis Expense records with expense codes, reimbursable flags, amounts, and approval status do not migrate to Microsoft Project. We export expense data as CSV. Microsoft Project does not include expense tracking. Customers requiring expense management post-migration should plan to use Microsoft Dynamics 365, Expensify, or a SharePoint-based expense request form built in Power Apps.

Celoxis

Portfolio

maps to

Microsoft Project

Project Online Project Spaces or Project for the web Roadmap

lossy
Fully supported

Celoxis Portfolios aggregate multiple projects under strategic groupings with portfolio-level KPIs and financial rollups. Microsoft Project lacks a native portfolio object. Project Online's Project Spaces and Project for the web's Roadmap feature provide partial portfolio visibility but do not include portfolio-level financial aggregation. We map portfolio membership (which projects belong to which portfolio) and flag that portfolio KPIs and rollup views require manual rebuild in Power BI or the Microsoft Power Platform.

Celoxis

Custom Apps

maps to

Microsoft Project

No equivalent

1:1
Not supported

Celoxis Custom Apps (Business and Enterprise tiers) create fully custom record types with their own forms, fields, and workflows. Microsoft Project has no equivalent concept. We export the data stored in Custom App records as CSV with the field definitions documented. The customer must rebuild the app structure in Power Apps or a custom SharePoint solution. Custom Apps are Celoxis-specific constructs and the app definition itself cannot be transferred.

Pair-specific challenges

  • Financial modules (Timesheet, Expense, Costing, Billing) do not exist in Microsoft Project

    Celoxis bundles timesheet submission, expense tracking, costing, and billing as paid add-ons or Professional-tier features. Microsoft Project (both desktop and Project Online) does not include any of these modules natively. We export timesheet and expense records as structured CSV but cannot load them into Microsoft Project because there is no destination object. The customer must procure a separate PSA tool (Dynamics 365 Project Operations, Productive, Mavenlink) or rebuild timesheet and expense entry in Power Apps if these workflows are required post-migration. We verify which financial add-ons are active on the source Celoxis account during scoping and adjust the migration object list accordingly.

  • Custom Apps have no Microsoft Project equivalent

    Celoxis Business and Enterprise tiers allow users to build fully custom record types with custom fields, forms, and workflows (Custom Apps). Microsoft Project supports only standard Project, Task, Resource, and Assignment objects plus user-defined custom fields. We export the data stored in Custom App records as CSV but cannot transfer the app definition, custom workflows, or custom form layouts. The customer rebuilds the app structure in Power Apps or a custom SharePoint solution using the field inventory we provide. This is a significant gap for customers who built Celoxis-specific business processes inside Custom Apps.

  • Risk and Issue objects do not migrate — only their data as CSV

    Celoxis Risk records (severity, probability, mitigation, owner) and Issue records (workflow states, priority, assignee) have no standard equivalent in Microsoft Project. We export these records as structured CSV with all fields preserved, but there is no native risk or issue register in Microsoft Project. Post-migration, the customer recreates these in SharePoint Lists, Microsoft Lists, a Power Apps risk register, or a dedicated GRC tool. The approval workflow state from Celoxis is not exportable and must be re-established in the replacement tool.

  • Report exports cap at 15,000 rows before security filters

    Celoxis applies a 15,000-row hard limit on report exports evaluated before security checks and custom field filters. We detect row counts during scoping and chunk large report exports into multiple passes, re-applying security context per chunk. If the source Celoxis account uses Data Isolation (Workspaces) on Enterprise, we run exports per workspace and merge the results. Projects exceeding the 15,000-row limit in a single export are split by date range or project subset.

  • Portfolio-level KPIs and financial rollups require Power BI rebuild

    Celoxis Portfolios aggregate project performance, resource utilization, and financial data across the portfolio in native dashboards. Microsoft Project has no portfolio aggregation feature — Project Online's Project Spaces provide project-level visibility but no portfolio-level financial rollup. We migrate portfolio membership (which projects belong to which portfolio) and all underlying project data, but portfolio dashboards, portfolio KPIs, and aggregated financial views must be rebuilt in Power BI using Microsoft Project data as the source. We provide the data model and recommended Power BI dataset structure to assist with this rebuild.

Migration approach

Six steps for a successful Celoxis to Microsoft Project data migration

  1. Discovery and source account audit

    We audit the source Celoxis account across tier (Essential, Professional, Business, Enterprise), active add-ons (Timesheet, Expense, Costing, Billing, Risk Management), custom field count and workspace isolation status, project count and task volume estimate, active Celoxis workflows and approval chains, and Celoxis API rate limit tier (150–1800 req/hour). We also identify the destination Microsoft Project version (desktop .MPP, Project Online, or Project for the web) and the customer's Microsoft 365 licensing tier since this determines which Project Plan (1, 3, or 5) is available. The discovery output is a written migration scope specifying which Celoxis objects have a destination, which require CSV export only, and which require a separate PSA or Power Apps rebuild.

  2. Data extraction from Celoxis API

    We extract Celoxis data using the REST API with rate-limit handling and exponential backoff appropriate to the source account's tier (150–1800 req/hour). We export Projects, Tasks, Task Dependencies, Resources, Resource Assignments, Baselines, Custom Fields, and — if present and active — Timesheet, Expense, Risk, and Issue records. Custom App record data exports as CSV with field definitions documented separately. We chunk large exports (over 15,000 rows) per the Celoxis export limit and re-apply workspace security context per chunk for Enterprise accounts using Data Isolation.

  3. Schema mapping and custom field translation

    We map Celoxis field names and types to Microsoft Project fields. Tasks map to Task rows with parent-child hierarchy preserved. Resources map to the Resource Sheet with cost rates mapped to Microsoft Project Cost Rate Table entries. Custom fields from Celoxis translate to Microsoft Project custom fields (Text, Number, Date, Flag, or Outline Code) where a type match exists. Celoxis-only constructs (Risks, Issues, Timesheet entries, Expenses, Custom Apps) are flagged as export-only with a field inventory delivered in CSV format. We resolve the Celoxis billing rate model — which has up to five override layers — to a single effective rate per resource and store it as a custom field in Microsoft Project since no native billing rate field exists.

  4. Sandbox or pilot migration

    We run a pilot migration into a test Microsoft Project file (desktop) or Project Online sandbox environment. For desktop MS Project, we generate a test .MPP file and validate task hierarchy, dependency graph, baseline slots, resource assignments, and custom field values against the Celoxis source data. For Project Online, we validate the migration using a non-production Project Online site. The customer spot-checks 25–50 randomly selected tasks, verifies resource assignments, and confirms that baseline data appears correctly. Any mapping corrections (field name mismatches, custom field type adjustments, dependency type corrections) are resolved here before production migration.

  5. Production migration in dependency order

    We run production migration in record-dependency order: Resources (Resource Sheet first because all assignments depend on it), Projects, Tasks with hierarchy and WBS, Task Dependencies (predecessors), Baselines, Resource Assignments, and Custom Fields. Custom field values are applied after the task structure is stable. Celoxis-only objects (Risks, Issues, Timesheet, Expense, Custom App data) are exported as structured CSV alongside the main migration and delivered as part of the handoff package. We do not load these into Microsoft Project because no destination object exists.

  6. Cutover, validation, and handoff

    We freeze Celoxis writes during cutover, run a final delta migration of any records modified during the migration window, and confirm the Microsoft Project file or Project Online environment is the system of record. We deliver the CSV export of Celoxis-only objects (Risks, Issues, Timesheets, Expenses, Custom App records) along with a written rebuild guide recommending Power Apps or SharePoint Lists as the destination for Celoxis risk, issue, and financial workflows. We do not rebuild Celoxis workflows or approval chains as Power Automate flows; we document the existing workflow structure and leave rebuild scope for the customer's admin or a Power Platform partner.

Platform deep dives

Context on both ends of the pair

Celoxis logo

Celoxis

Source

Strengths

  • Integrated financial tracking with project-level cost rates, billing rates, and budget vs. actuals in a single view.
  • Multi-baseline scheduling with critical path analysis built directly into the interactive Gantt chart.
  • Resource workload and conflict management with capacity visualization across the portfolio.
  • Tiered API with up to 1800 requests/hour on Enterprise for high-volume integrations.
  • Both cloud (SaaS) and on-premise (Linux + PostgreSQL) deployment options.

Weaknesses

  • No native mobile app — mobile users must access via a browser which offers limited functionality.
  • Dated UI compared to newer PM tools; visual design has not kept pace with modern UX expectations.
  • Steep learning curve for new users — the depth of features overwhelms teams used to simpler tools.
  • Risk Management, Timesheet, Expense, and Billing are paid add-ons rather than core features.
  • Full-text document search was removed in v15 — document content is no longer indexed, only metadata.

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.

Most migrations land between two and four weeks for accounts with up to 50 projects, clean task hierarchies, and no active financial add-on modules (Timesheet, Expense, Costing, Billing). Migrations with active financial modules, Celoxis Enterprise Custom Apps, large risk and issue registers, or Enterprise-tier workspaces with Data Isolation move to six to ten weeks because of extended scoping, CSV export packaging, and the Power Apps rebuild handoff work.
