At 3:50am I began upgrading Unity42(1)for DST. This includes zupdater.jar upgrade for Java and CU4.2(1)_ES59.exe. I upgraded both primary and secondary Unity and tested. I found the secondary was working failing over from primary. After checking the SQL Enterprise Manager for primary Unity, the DB is completely gone. Has anyone experienced this issue during DST upgrade? We are accomplishing Legato SQL backups every evening. I do have a backup at 1:00am prior to the upgrade. Question.... Can I restore the db and expect VM to be lacking up to that backup even though I have a backend exchange server for message store only?
