As Microsoft phases out Project Online, organizations need an alternative, and FluentPro offers migrations from Project Online to Planner Premium and from Project Online to Project Server.
When evaluating a move away from Project Online, it is important to understand the differences in what will carry over and what will be lost. This article highlights the key features and considerations of both migration paths.
Planner Premium is well-suited for small teams that require simple task tracking, quick collaboration, and seamless integration with Microsoft 365 apps, such as Teams and Outlook. However, migrating from Project Online to Planner Premium comes with significant trade-offs. Critical data, including detailed project schedules, baselines, portfolio structures, resource capacity planning, workflows, and advanced reporting, will not be preserved. For organizations with established PMO practices, this means a major reduction in functionality and governance.
Project Server Subscription Edition, by contrast, requires more effort and infrastructure to migrate, but it provides a far richer outcome for enterprises. It retains advanced portfolio and resource management, supports custom workflows and governance processes, and allows for comprehensive reporting (e.g., through Power BI). While the setup is more complex, this transition ensures continuity for organizations that rely on structured project management, compliance, and enterprise-grade oversight.
Migration from Project Online to Project Server or Planner Premium uses two separate FluentPro tools: FluentBooks (a desktop app for migrating to Project Server) and Project Migrator (an online tool for migrating to Planner Premium).
Key Migration Risks:
- Moving to Planner Premium: Customers lose enterprise PMO features (resource pool, portfolio management, baselines, custom reports, workflows). Migration results in only tasks/checklists surviving.
- Moving to Project Server: Requires infrastructure and effort, but most data and features can be migrated/recreated, ensuring continuity for PMOs and regulated industries.
Migration & Feature Comparison: Project Online → Planner Premium vs. Project Server Subscription Edition
|
Feature / Aspect from Project Online |
Project Server Subscription Edition |
Planner Premium |
| Deployment/Migration effort | On-premises (customer infrastructure) | Microsoft 365 cloud only. |
| Project Structures | Full support for project schedules, WBS, dependencies, and baselines. Migration from Online is largely supported. | Only task boards and basic schedules are migrated (including WBS and dependencies). Detailed project plans (baselines) will not migrate. |
| Target Audience | Enterprises / PMOs needing full project portfolio management. | Small agile teams needing lightweight task tracking. |
| Resource Management | Enterprise-grade resource pool, capacity planning, and timesheets supported. Resource data can migrate from Online. | Very limited, only task assignment at the team level. Enterprise resource pool, capacity planning, and timesheets will be lost. |
| Users and Resources | Users themselves are not migrated from the source to the target tenant; they need to be created in the Azure AD before migration. Resources are migrated to the Resource Pool, and users are mapped during migration from the source to the target ones. | Users themselves are not migrated from the source to the target tenant. Users assigned to tasks must exist in the target tenant. Assignments will be migrated only if source users are mapped to corresponding target users. However, if you choose to create bookable resources without associated users on the mapping step, the assignments linked to those resources will also be migrated. |
| Portfolio & Program Management | Portfolio management is supported for migration (including portfolio analysis). | Not available. Portfolio-level data, prioritization, and demand management will be lost. |
| Workflows & Governance | Full workflow and governance features. SharePoint workflows created in SharePoint Designer are supported. | Not supported. Custom workflows, stage gates, and approvals cannot be migrated. |
| Master projects and Subprojects | Fully supported for migration from Project Online, preserving the structure and hierarchy. | Migrated as separate projects. |
| Enterprise Calendars | Fully supported for migration. | Need to be recreated manually on the target. |
| Tasks in the Schedule | All tasks from the schedule will be migrated, regardless of the number, as they are fully supported for migration. | The maximum total tasks for a schedule is 3000. If there are more than 3,000 tasks in a project, only the first 3,000 will be migrated; the remaining tasks will be skipped. |
| SharePoint Root PWA site settings and Project Sites | Fully supported for migration. | Not supported for migration. |
| Version History / List Data | Not preserved. SharePoint Document/Item versions won’t migrate. | Not preserved. Detailed version history from Online lists won’t migrate. |
| Reporting & Data Access | Custom reporting from Online can be rebuilt, and reports that use OData will be migrated. | Basic dashboards only, Power BI for tasks. |
| Integrations | Project Online integrations are often reconfigurable. | Deep with Teams and Outlook |
| Security & Permissions | Full RBS, custom permissions, granular governance, and SharePoint permissions can be migrated. | Simplified. Granular RBS permissions and custom security models will be lost. |
