Upgrade 12 to 14 – Rollback
I’m planning on upgrading from SEP12 to 14 and would like to know if it crashed what would be the rollback plan?
Or do not have a rollback plan? Should failure attempt to uninstall? Or install SEP 12 and perform restore?
Before upgrading, do I recommend clearing / deleting some folders for better performance in the upgrade?
Run “truncate transaction log”? And run “rebuild indexes”?
