Project Online is retiring: your roadmap to OnePlan

For many Microsoft organisations, Project Online has quietly run the portfolio for a decade. Its retirement is not a minor tooling change — it touches schedules, resources, timesheets, financials and years of reporting history. The instinct is to find the nearest like-for-like replacement and move on. That instinct is a mistake.

The transition is the perfect moment to evolve your PPM strategy, shifting the focus from simple project tracking to delivering real business value. OnePlan is the natural evolution for Microsoft users — an AI-enabled strategic portfolio, financial, resource and work management platform that lives natively inside Microsoft 365.

Migrate the data and you keep the past. Rethink the model and you change the future.

Start with the model, not the data

Most failed migrations start by exporting everything and trying to recreate it. Start instead with the operating model: which portfolios, which intake process, which approvals, which financial and resource model. OnePlan is flexible enough to fit every organisation’s needs — so decide what “good” looks like before you move a single project.

What to move, what to retire

Not everything in Project Online deserves a second life. We classify your estate into three buckets:

• Move — active projects, resource pools, financial actuals and the reporting history that proves trends.
• Transform — custom fields, workflows and SharePoint artefacts that map to a cleaner OnePlan model.
• Retire — abandoned sites, duplicate templates and reports nobody has opened in years.

Preserve the history that matters

Trend lines are credibility. We migrate the actuals and snapshots that let you show three years of delivery performance on day one — then surface them through AI-enabled Power BI analytics so leadership sees value, not just status.

Mitigate the risk of the deadline

End-of-life dates concentrate minds, but rushed cut-overs break trust. A phased migration — pilot portfolio first, full estate second — lets you leverage deep historical expertise for a seamless move while the old system is still available as a safety net.
