Overview

What this migration involves

Moving from ONES.com to Microsoft Project is a structural migration that requires mapping a multi-object development-management schema onto a Gantt-centric scheduling model. ONES.com organizes work as Projects containing Tasks with parent-child hierarchies, Requirements linked to Tasks, Sprints grouping Tasks, and Bugs as a separate work-item type. Microsoft Project uses a Project file containing Tasks with WBS (Work Breakdown Structure) hierarchy, Dependencies, and Resource assignments. We export the ONES.com project tree first, then map subtasks to outline levels, Requirements to milestone or summary tasks, and Bugs to Tasks with a custom field flagging the original work-item type. Sprint associations do not have a native Microsoft Project equivalent; we flatten sprint groupings into a custom Start-to-Finish date range per summary task. Automation rules and pipeline configurations are not portable and are inventoried separately for manual rebuild. We deliver the migrated .mpp or cloud-project file plus a written mapping document covering every non-standard field and any custom ONES field requiring a custom column in Microsoft Project.

Why teams make this switch

Two sides of the same decision

Leaving

ONES.com logo

ONES.com

What's pushing teams away

  • Interface complexity and learning curve can be steep for non-technical team members, especially compared to simpler project management tools.
  • Performance slowdowns reported on larger projects with extensive task histories, particularly in the on-premises version.
  • The platform is opinionated toward software development workflows, making it less flexible for non-technical project management use cases.
  • Limited third-party integrations outside the Atlassian ecosystem compared to general-purpose project management platforms.

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 ONES.com objects map to Microsoft Project

Each row shows how a ONES.com 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.

ONES.com

Project

maps to

Microsoft Project

Project File (.mpp) or Project Online Project

1:1
Fully supported

Each ONES.com Project maps to one Microsoft Project file (MPP) or one Project Online project. We extract the project name, description, start date, and target end date and create the destination project structure before any tasks are inserted. Multi-project organizations with shared resource pools may need a Project Server or Project Online Enterprise Resource Plan (ERP) configured, which we flag during scoping.

ONES.com

Task

maps to

Microsoft Project

Task

1:1
Fully supported

ONES.com Tasks map directly to Microsoft Project Tasks. We preserve the task name, start date, finish date, percent complete, priority, assignee (mapped to Project Resource), and the parent-child hierarchy by setting the WBS outline level. Subtasks in ONES.com become indented tasks under their parent summary task. Predecessor dependencies (Finish-to-Start, Start-to-Start, etc.) from ONES.com task links migrate as Project predecessor relationships using the predecessor task ID.

ONES.com

Sprint

maps to

Microsoft Project

Custom Start/Finish Date Range (summary task or flag field)

lossy
Fully supported

Microsoft Project has no native Sprint object. We handle this in one of two ways depending on the customer's reporting needs: (1) create a summary task per Sprint with its start and end date as the task start/finish, and nest the sprint's assigned Tasks under it, or (2) add a custom Text field (Sprint Name) and two date fields (Sprint Start, Sprint End) to the task template and populate them from the ONES.com Sprint assignment. We agree on the approach during scoping based on whether the customer uses sprint velocity or burndown reporting in Microsoft Project.

ONES.com

Requirement

maps to

Microsoft Project

Milestone or Summary Task with custom field

lossy
Fully supported

ONES.com Requirements are distinct work items capturing product specifications. Microsoft Project has no native Requirements object. We map Requirements to either Milestone tasks (if the Requirement has a single deliverable date) or Summary Tasks (if it wraps multiple child Tasks) with a custom Text field (Requirement ID) and a custom Text field (Requirement Status) carrying the original ONES.com status. TestCase linkage from ONES.com does not migrate; we document TestCase-to-Requirement links in the handoff report for the customer's QA team to reassign manually.

ONES.com

Bug

maps to

Microsoft Project

Task with custom Type = Bug field

1:1
Fully supported

ONES.com Bugs map to Microsoft Project Tasks with a custom Text field (Work Item Type) set to 'Bug' and a custom Text field (Bug Severity) carrying the ONES.com severity value. Steps-to-reproduce and environment details from ONES.com are stored in the Task Notes field as structured text. We flag any Bug that was linked to a Task in ONES.com by adding the predecessor Task ID to a custom Text field (Linked ONES Task) in the Microsoft Project file.

ONES.com

User / Member

maps to

Microsoft Project

Resource

1:1
Fully supported

ONES.com project members map to Microsoft Project Resources. We extract the member name and email, create a Resource record in the destination project, and map the ONES.com assignee field to the Resource Assignment. If a member in ONES.com has no corresponding user in the destination Microsoft Project environment (common for .mpp file migrations without a PWA connection), we create the Resource as a generic resource with the name and note it for the admin to link to an Active Directory account post-migration.

ONES.com

Custom Field (Task-level)

maps to

Microsoft Project

Custom Field (Task)

lossy
Fully supported

ONES.com custom fields on Tasks (text, number, date, dropdown, user reference) map to Microsoft Project custom fields. We use the equivalent Microsoft Project custom field type: Text fields for string values, Number fields for numeric values, Date fields for date values, and Flag or Outline Code fields for dropdown selections. We define the custom field set in the destination project template before data import and preserve the ONES.com field label in the column header name.

ONES.com

Wiki Page

maps to

Microsoft Project

Not Migrated

1:1
Fully supported

ONES.com Wiki pages do not have a migration path to Microsoft Project. Microsoft Project (desktop and PWA) has no native wiki or documentation storage. We extract the page tree and content during discovery and deliver it as a Word (.docx) export organized by project folder. The customer's admin stores these alongside the .mpp file in SharePoint or a document management system. Wide-table pages are exported as Word to avoid the PDF truncation issue documented in the ONES.com source platform context.

ONES.com

TestCase

maps to

Microsoft Project

Not Migrated

1:1
Fully supported

ONES.com TestCases managed in ONES TestCase are not migrated to Microsoft Project. TestCases contain test steps, expected results, and pass/fail history that have no equivalent in Microsoft Project. We extract TestCase records as a structured CSV export organized by Requirement ID so the customer's QA team can import into their chosen test management tool (Azure Test Plans, qTest, TestRail, or Zephyr) post-migration.

ONES.com

Automation Rules

maps to

Microsoft Project

Not Migrated

1:1
Not supported

ONES.com automation rules (trigger-action logic for task status changes, assignments, notifications) are not exposed via any documented export endpoint and cannot be migrated. We identify all active automation rules during discovery and deliver a written inventory listing each rule's trigger, conditions, and actions with a recommended manual rebuild approach. Microsoft Project does not have native automation; rebuild options are Microsoft Power Automate (for Project Online) or VBA macros (for Project Desktop), scoped separately.

ONES.com

Pipeline / CI-CD Configuration

maps to

Microsoft Project

Not Migrated

1:1
Fully supported

Pipeline definitions in ONES Build and ONES Pipeline are tightly coupled to the ONES execution environment and connected repositories. These cannot be exported or migrated. We migrate Build and TestCase records as data but note that the CI/CD pipeline definitions must be rebuilt in the destination platform (GitHub Actions, Azure DevOps Pipelines, or Jenkins) post-migration. This is documented in the handoff report with a pipeline reconstruction checklist.

Pair-specific challenges

  • Sprint associations have no native Microsoft Project equivalent

    ONES.com Sprint is a named time-boxed iteration that groups Tasks and carries its own start/end dates and goal. Microsoft Project has no Sprint object, Kanban board, or iteration concept natively. We resolve this by either nesting sprint-grouped Tasks under a summary Sprint task with locked dates, or by adding a Sprint Name custom field to the task template and populating it from ONES.com. Either approach requires the customer to choose during scoping, and neither preserves the sprint velocity or burndown charts that ONES.com generates automatically. Teams relying on sprint metrics must rebuild those reports in Microsoft Project manually or via Power BI after migration.

  • Requirements and TestCases require manual rehousing

    ONES.com Requirements are distinct from Tasks and link to both Tasks and TestCases. Microsoft Project has no native Requirements object, and ONES.com TestCases have no equivalent in Microsoft Project. We extract Requirements as structured data and map them to Milestone or Summary Tasks with a custom Requirement ID field, but the linkage semantics (which TestCases verify which Requirements) do not migrate. The customer's QA and product teams must re-establish these relationships in their destination test management tool (Azure Test Plans, TestRail, Zephyr) post-migration. We deliver a Requirements-to-Task linkage map to assist that rebuild.

  • ONES Wiki wide-table export truncates content to PDF

    ONES.com Wiki pages with tables exceeding approximately 720px width are scaled down and may be truncated when exported as PDF. This is a source-platform gotcha that surfaces during documentation extraction. We flag wide-table pages during the migration audit and export those pages as Word (.docx) files instead, which preserves full table content. We apply this selectively to avoid exporting the entire wiki as Word when only a subset of pages is affected.

  • Automation rules are not portable and must be rebuilt

    Automation rules configured in ONES Project are not exposed via any documented migration API. Any trigger-action logic (task status changes triggering assignee notifications, field-update cascades, sprint-start automations) must be manually recreated post-migration. We identify all active automation rules during discovery, document each rule's trigger, conditions, and actions in a written inventory, and note whether the rebuild target is Microsoft Power Automate (for Project Online) or VBA (for Project Desktop). This inventory is delivered before cutover so the customer can plan the rebuild effort in parallel with migration.

  • Resource booking and resource management may require manual entry

    ONES.com assigns members to Tasks at the project level. Microsoft Project Resources can be assigned with hours (Resource Units) rather than binary assignments. If the ONES.com team uses only assignee-level task assignment without time estimates, the migration maps the assignee to a 100% unit Resource Assignment. If the team used ONES.com time tracking, those hours must be manually entered as Resource Units in the Microsoft Project plan post-migration because ONES.com does not export billable hours in a format that maps directly to Project's resource allocation fields.

Migration approach

Six steps for a successful ONES.com to Microsoft Project data migration

  1. Discovery and project inventory

    We audit the source ONES.com environment across all projects in scope: project count, task hierarchy depth (max subtask levels), active sprints, Requirements and Bug counts, custom field definitions on Tasks and Bugs, and active automation rules. We extract the full task tree via ONES.com export (CSV or API response) and flag any project with more than 500 tasks, more than three levels of subtask nesting, or any Requirements or TestCase linkage as a complexity flag. We also inventory the ONES.com Wiki pages and TestCases for separate export. The discovery output is a written migration scope with record counts, complexity assessment, and a yes/no decision on the Sprint mapping approach.

  2. Sprint mapping strategy and template setup

    We define the Sprint mapping approach agreed during scoping: either summary-task nesting or custom Sprint Name/Start/End fields on the task template. We configure the destination Microsoft Project file (MPP or Project Online project) with the custom fields, column layout, and WBS numbering scheme. If the destination is Project Online, we also provision the Enterprise Resource Pool and map ONES.com members to Active Directory user accounts. This step creates the destination shell before any data is inserted.

  3. Data extraction and transformation

    We export Projects, Tasks, Requirements, Bugs, and sprint assignments from ONES.com in structured CSV format. We transform the data: subtasks are indented under parent task outline levels, predecessor links are converted to predecessor task IDs, sprint assignments are applied to the Sprint Name field or a summary Sprint task, Requirements are converted to Milestone or Summary Tasks with the Requirement ID custom field, and Bugs are converted to Tasks with Work Item Type = Bug and Bug Severity populated. Custom field values are mapped to their corresponding Microsoft Project custom field types. We run the transform in a staging environment before the destination project file is touched.

  4. Sandbox import and reconciliation

    If the destination is Project Online, we import into a non-production project site to validate the structure. For .mpp file migrations, we open the file in Microsoft Project Desktop to verify hierarchy, dependencies, and custom field population. The customer's PM lead spot-checks 20-30 tasks across different projects for data accuracy: parent-child relationships, dates, assignee resolution, and sprint-date mapping. We correct any mapping errors before the production import. Custom field validation is confirmed here because once the template is finalized, changes require reimporting the data.

  5. Production migration and cutover

    We import the transformed data into the production Microsoft Project file or Project Online site. The import runs in dependency order: project metadata first, then task hierarchy (to establish outline levels and summary task relationships), then predecessor links (resolved against the newly assigned task IDs), then custom fields, then resource assignments. Wiki pages and TestCases are delivered as separate exports (Word .docx for Wiki, CSV for TestCases) on the same day as cutover. We run a final reconciliation report comparing source record counts to destination record counts and flag any gaps for manual review.

  6. Handoff and automation rebuild inventory

    We deliver the migrated Microsoft Project file, the Wiki Word export organized by project folder, the TestCase CSV organized by Requirement ID, and the automation rules inventory document. We support a five-business-day window post-cutover to resolve any data reconciliation issues raised by the PM team. We do not rebuild automation rules, configure Power Automate flows, or create VBA macros as part of the standard migration scope; those are separate engagements. We do not configure Microsoft Project Online resource plans, SharePoint document library linkages, or Power BI reporting dashboards in the standard scope.

Platform deep dives

Context on both ends of the pair

ONES.com logo

ONES.com

Source

Strengths

  • Covers the full software development lifecycle from requirements through release within one product family.
  • Purpose-built Jira and Confluence migration tooling for teams switching from Atlassian.
  • Supports both cloud and on-premises (On-Prem) deployments for regulated environments.
  • Task hierarchy with subtasks, linked requirements, sprint planning, and time tracking in one tool.
  • TestCase management integrates with Requirements and Builds for end-to-end traceability.

Weaknesses

  • Automation rules and pipeline configurations are not portable across platforms and must be rebuilt manually.
  • Steep learning curve for non-technical users due to development-focused UI and terminology.
  • No publicly documented migration API covering all ONES product data types.
  • Performance degrades on large projects with extensive historical data in on-premises deployments.
  • Limited integrations outside the Atlassian ecosystem compared to general PM tools.

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 three and five weeks for up to 5 projects with fewer than 2,000 tasks and no Requirements-to-TestCase linkage complexity. Migrations with 10+ projects, deep subtask nesting, Requirements mapping to milestones, Bug-to-task conversion with custom field carry-over, or sprint-date-range configuration move to six to ten weeks because of WBS structure design, custom column configuration, and cross-record validation. The wiki and TestCase exports run in parallel but do not extend the timeline significantly.
