Microsoft retired Project Online on September 30, 2026. If your tenant is still accessible, treat it as borrowed time: Microsoft can switch it off without further notice. Export your data and plan the move now.
Whether you're evaluating Project Server Subscription Edition, Planner Premium + Teams4PM or OnePlan, the right migration strategy starts with understanding how your organization actually manages projects today.

Microsoft retired Project Online on September 30, 2026.
Since then:
Organizations delaying planning often underestimate how much coordination, testing, governance, and user readiness a successful migration requires.
The teams seeing the smoothest transitions are not the ones moving the fastest. They’re the ones starting early.
The organizations we work with that have the smoothest migrations are the ones that started planning early. Not the ones that moved the fastest. A successful migration involves evaluating target platforms, understanding your data, testing with real project data, training your team, and building confidence before you cut over.
Rushed migrations introduce risk: data loss, user adoption failures, and disruption to active projects. None of those are acceptable outcomes when the goal is protecting the work your team has built.
Unsupported since September 30, 2026.
If you haven't started, begin with an assessment now.
