Error Unsupported database format when upgrading RMAD (4327216)

During an in-place upgrade of RMAD, the installation proceeds as expected until the final stage. At that point, an error message appears stating "Unsupported database format!", and the upgrade process is automatically rolled back.

There is an issue with the existing ERDiskAD.mdb or RMAD.db3 file, which may be corrupt or empty (0 KB). As a result, when the dbimport tool attempts to import it into RMAD.db3, the process encounters errors.

WORKAROUND

• Navigate to the RMAD installation folder (Default: C:\ProgramData\Quest\Recovery Manager for Active Directory\).
• Locate the ERDiskAD.mdb or RMAD.db3 file.
• Check for older versions of the file, such as:
  • ERDiskAD_2021_08_05-10_50_16.mdb
  • RMAD_2024_08_05-10_50_16.db3
• If an older version exists, rename it to ERDiskAD.mdb or RMAD.db3.
• Re-run the installation and verify if the issue is resolved.
