Run the audit: Step by step

Detailed workflow

In this example workflow, you are migrating your project from Archicad 25 to Archicad 28.
  1. Make a copy of your current project and save it as a backup, just in case.
  2. Open both versions of Archicad on your computer
  3. Download the Project Migration Audit Add-on
  4. Use Archicad’s Add-On Manager to add it to both versions of Archicad:
    • Go to Options > Add-on Manager, click Add, then browse for the Add-on file that you downloaded: ProjectMigrationAuditAdd-on.apx

    • For more info on Add-on Manager: see Archicad Help
  5. Download and install the Project Migration Audit Tool to your computer
  6. Open your project in Archicad 25
  7. Migrate the project to Archicad 28:
    • For a solo project: just open it in Archicad 28
    • For a Teamwork project: run the Teamwork Migration tool. See Archicad Help
  8. In Archicad 25, prepare a reference file: use File > Prepare for Migration Audit. This command prepares a reference file needed for the audit. This might take some time. If you cancel, you will have to start over from the beginning the next time. When prompted, save the reference file (.pmax) to a chosen location.
  9. In Archicad 28, do it again: prepare another reference file by using File > Prepare for Migration Audit. When prompted, save the reference file (.pmax) to a chosen location.
  10. Open the Project Migration Audit Tool.
  11. If this is your first audit, you see the welcome screen. You’ve already prepared the reference files, so click Let’s Audit to proceed.

  12. The Start Project Audit dialog appears:
    • Browse the two .pmax reference files that you saved (one each for Archicad 25 and Archicad 28): drag and drop them onto the screen, or click to browse the file location
    • The earlier version goes on the left, the later version goes on the right


    • If something is off, you’ll get a warning message - for example, if the two reference files contain different numbers of layouts, or if both reference files are from the same Archicad version
  13. Click Start Audit. Wait while the audit runs its course.
  14. Your audit is ready! Dive into the Layout Compare window to see the result.
