We Won't Retire
In 6 Months.
Microsoft is retiring Project Online. Test a migration flow in Timezylla with Gantt, Grid, resources, baselines, stakeholder views, and AI-assisted plan review.
The clock is ticking.
Here's the retirement timeline Microsoft set.
New tenants blocked
No new organizations can provision Project Online.
SharePoint workflows broke
Legacy workflow integrations stopped functioning.
Full retirement
Project Online goes dark. All data inaccessible.
Two ways to import for approved migration teams.
Bring your MS Project XML, Excel, or CSV files. We help validate the rest.
Standard Import
Your data, your timeline, no changes.
- Import MS Project XML, Excel, or CSV files
- All tasks, dates, and dependencies preserved
- Swimlane structure auto-detected
- Milestone validation included
- Pilot checklist for data review
AI-Enhanced Import
Your project, but better.
- Everything in Standard Import, plus:
- AI rewrites vague task names into clear actions
- Auto-infers missing dependencies
- Creates logical swimlanes from flat task lists
- Risk detection — flags unrealistic timelines
- Duration confidence scoring
The Project Online workflows migration teams ask us to preserve. Plus everything it didn't.

Questions from the migration queue
Answers grounded in Microsoft's retirement announcement + migration community research.
What exactly happens to my data on September 30, 2026?
Microsoft will delete Project Online schedules, resource data, and linked SharePoint sites from their servers on the retirement date. Back up your plans before then — ideally import them into Timezylla now so you have a working copy alongside your existing tenant.
Why not just use Planner Premium (Microsoft's recommended path)?
Planner Premium is a different product with no native MPP support, no true global resource pool, and no advanced timesheet features. Project Online users typically describe it as a step backward. Project Server Subscription Edition keeps more features but requires you to run on-prem or in Azure — another migration project in itself.
Will my existing Project Online exports import cleanly?
Timezylla's importer is designed for MS Project XML, Excel, CSV, and Jira sources. We ask migration teams to validate task counts, dates, dependencies, resources, and milestones against the original before trusting the plan.
How long does a typical Project Online migration take?
Start with one representative project, then measure. A single-project pilot can usually be reviewed much faster than a portfolio rollout, but multi-project moves need time for validation, stakeholder review, and workflow cleanup.
What happens to my team during the switch?
Treat Timezylla as a pilot workspace first. Keep the source plan read-only until the migrated plan has been validated and the team can run a real project meeting from the new workflow.
What migration teams help us validate.
Migration validation focuses on real project plans, not demo data.
Import validation
Can a project manager trust the imported dates, dependencies, and milestones?
Stakeholder review
Can a sponsor understand the plan without rebuilding it in slides?
Workflow fit
Can the team run its next planning meeting from the migrated workspace?
