Project Online retires September 30, 2026.

What does the preview show?

Checks compatibility across 4 dimensions

Tasks, dependencies, resources, and constraints — each bucket gets a transferability score you can see at a glance.

Surfaces gaps with specific guidance

Every feature that migrates with loss, needs review, or isn't supported gets a one-sentence action item explaining what to do.

Shows what you gain

Picks 4-6 Onplana capabilities relevant to your file — resource capacity planning, AI risk detection, real-time collaboration.

Renders a Gantt preview

See your project bars color-coded by transfer status before you move a single row to a new tool.

How it works

1

Upload your file

Drag and drop a .mpp or MSPDI .xml file. We accept files up to 50 MB.

2

Get an honest analysis

Our MPXJ parser reads the file; the analyzer scores compatibility and surfaces every feature gap.

3

Review and decide

Scan the dashboard, click through gaps, get the PDF emailed for sharing with your team.

What happens to your file?

We parse your .mpp / .xml into memory, run the compatibility analysis, and generate the preview you see above. The source file bytes are not persisted — we discard them after parsing.

What we do keep: the parsed task/dependency/resource counts (for the preview you just saw) and the generated compatibility report. These are associated with a random analysis ID and, if you enter your email to unlock the PDF, the hashed email for deduplication.

We never see the contents of your project beyond what's in the preview above. No data is shared with third parties or used for training.

Frequently asked questions

Your migration preview is free.

When you're ready to migrate for real, Onplana's one-click import preserves the tasks, dependencies, and baselines your preview showed as transferable.
