Microsoft Project Online is approaching its September 30, 2026 end-of-service date—but what comes next isn't as simple as clicking an upgrade button.

In the first episode of Support Engineering Weekly, we take a deep technical look at what the retirement means for organizations that have spent years building projects, workflows, reporting, integrations, governance and operational processes around Project Online.

We begin with the retirement timeline and clarify what is—and isn't—being retired. From there, we examine one of the biggest misconceptions surrounding the transition: the assumption that Planner Premium is simply a modernized version of Project Online.

The discussion then goes beneath the user interface to explore the architectural differences between basic Planner and Planner Premium, including the role of Microsoft Dataverse, data organization, governance, dependencies and scale.

We then examine the major transition paths available to organizations:

• Planner Premium for collaborative project execution and modern work management.
• Project Server Subscription Edition for organizations that continue to require enterprise PPM, on-premises control and deep customization.
• Dynamics 365 Project Operations for project-centric organizations that need broader project, resource, time, expense and financial capabilities.

The conversation also looks at migration as a modernization exercise rather than a simple lift-and-shift operation, including environment assessment, legacy workflows, reporting, OData integrations, APIs, permissions, governance and technical debt.

Finally, we explore what increasingly structured and governed project data could mean for AI-assisted work management—and how the role of the project manager may evolve as more mechanical project-management activities become automated.
