Overview
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.
Every standard and custom field arrives verified.

Object mapping
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
Microsoft Project
Project File (.mpp) or Project Online Project
1:1Each 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
Microsoft Project
Task
1:1ONES.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
Microsoft Project
Custom Start/Finish Date Range (summary task or flag field)
lossyMicrosoft 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
Microsoft Project
Milestone or Summary Task with custom field
lossyONES.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
Microsoft Project
Task with custom Type = Bug field
1:1ONES.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
Microsoft Project
Resource
1:1ONES.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)
Microsoft Project
Custom Field (Task)
lossyONES.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
Microsoft Project
Not Migrated
1:1ONES.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
Microsoft Project
Not Migrated
1:1ONES.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
Microsoft Project
Not Migrated
1:1ONES.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
Microsoft Project
Not Migrated
1:1Pipeline 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.

Migration approach
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.
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.
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.
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.
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.
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.
