Downgrading a Database

Return a Database to the Previous Version

Sometimes after a new version of Calibration Control (our Calibration Management Software) is deployed a decision is made to return to a previous version.  Unfortunately, many Ape updates include changes to the database which cannot be uninstalled as easily as the software.  This is why a manual database backup is strongly encouraged before updating the MS SQL Server database.

Restore an Access Database

  1. Refer to the Folders used by Ape help topic before continuing.
  2. Open the Data folder and rename the apecal.mdb file (e.g., higher-version-apecal.mdb).
  3. In the Backup folder under the Data folder, rename the most recent database backup file from apecal-auto-backup-[long number].dbk to apecal.mdb.
  4. Install the previous version of Ape or download and install one of the older Ape versions that your product key works with.
  5. Restart the previous version of Ape to confirm that the database works.

Restore a SQL Server Database

Use the same instructions in the Installing SQL Server help topic – Restore (1st Method), but choose the file that was backed up as part of the update process.
