The upgrade might work successfully when using the
IGNOREVALIDATIONERRORS switch during the upgrade. But, it's still needed to disable the SQL mirror during the upgrade:
- Leave the availability group in place.
- Disable SQL mirroring for the ePO database.
- Leave <ePO installation directory>\Server\conf\orion\db.properties to be directed to the availability group or virtual name.
- Run the ePO upgrade with the IGNOREVALIDATIONERRORS=1 switch using the following command:
"<ePO_installation_directory>\setup.exe" IGNOREVALIDATIONERRORS=1
- Enable SQL mirroring for the ePO database. This action allows SQL to handle the replication of any changes made to the database during the upgrade.
If this action doesn't work, you might need to disable the SQL availability group as well. Point ePO to the physical SQL Server name, as explained in the "Solution" field above.
