Preview what a plan keeps before you migrate

All plansMember

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.

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 Planner and Microsoft To Do, from inside Onplana. Move the plan into Onplana, then open the project menu, choose Export to Microsoft, and connect your Microsoft 365 account. Planner gets a new plan where each top-level task becomes a bucket holding the tasks beneath it, with their due dates; Planner does not keep dependencies. To Do gets a new list of the plan’s tasks with their due dates, without the summary tasks. Live now.
  • Microsoft Project for the web, Microsoft Lists, and other tools, scored in the preview so you can plan the move. The tool does not write to them.

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.

This preview takes those four formats only. A ProjectLibre .pod or GanttProject .gan plan imports straight into Onplana instead, through Import a Microsoft Project file.

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 Microsoft Planner or To Do, migrate into Onplana first and export from your project; for any other destination, 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.
