Preview what a plan keeps before you migrate

All plans Member

Before you move a Microsoft Project plan anywhere, you can see exactly what each destination keeps and what it drops. Upload the file, and Onplana reads the real schedule (task hierarchy, dependencies, dates, percent complete, cost, and custom fields), then scores every destination and lists in plain language what transfers cleanly and what needs a look, so you commit knowing what survives.

Microsoft Project Online retires on September 30, 2026, which is why many teams are picking a destination now.

Where you can migrate to

Section titled “Where you can migrate to”

Every destination gets a 0-100 fidelity score in the preview. What you can actually do with each one today:

  • Onplana, the highest-fidelity destination. The work breakdown, dependencies, cost, and custom fields all carry over; a few things change shape (task notes arrive as attachments, and calendar exceptions import separately), and the preview names them for your file. Live now.
  • Microsoft Excel, CSV, and Microsoft Project XML (MSPDI), portable files you can download right away, no sign-in. Live now.
  • Microsoft Project for the web and Microsoft Planner, with the task tree and dependencies carried across. Rolling out (connect your Microsoft 365 account to write directly).
  • Microsoft To Do, Microsoft Lists, and other tools, scored in the preview today; direct write is on the way.

Supported source files

Section titled “Supported source files”

.mpp (Microsoft Project desktop), .mpx, .xer (Primavera P6), and Microsoft Project XML / MSPDI .xml. Up to 50 MB.

Preview a file

Section titled “Preview a file”

  1. Upload your file. Choose a .mpp, .mpx, .xer, or .xml file.

  2. See the fidelity preview. Each destination shows a score plus a “carries over cleanly” vs “needs a review” breakdown: which dependencies survive, whether cost and custom fields make it, where the hierarchy is flattened.

  3. Pick a destination. Download a file target (Excel, CSV, MSPDI), or migrate into Onplana with full fidelity. For a Microsoft cloud destination that is live, connect your Microsoft 365 account to write into it directly; otherwise download a file and import it there.

Why fidelity differs by destination

Section titled “Why fidelity differs by destination”

Different destinations keep different things. A flat list cannot store a dependency; a basic task board cannot store cost. The preview is honest about this up front, so you choose the destination that keeps what you care about, rather than discovering the loss after the migration. Onplana shows the least loss of any destination.

FAQs

Section titled “FAQs”

Is it free? Yes. Previewing any plan and exporting the file formats (Excel, CSV, MSPDI) is free on every plan, and migrating into Onplana is free too: it creates a normal project on your plan.

Does it change my original file? No. The tool only reads your uploaded file; it never modifies it.

What about resources and assignments? Resource assignments carry into Onplana. Most other destinations do not keep them, and the preview flags that per destination.

How big a file can I upload? Up to 50 MB, in .mpp, .mpx, .xer, or MSPDI .xml form. If Onplana is where you are headed anyway, Import a Microsoft Project file gives a faster single-destination compatibility report.
