We are currently running Veritas 9.0. We tried to upgrade to version 10.1 and had a database error issue during the upgrade. We had Veritas support work on the issue for a few hours with no luck. They tried to do a repair installation and when we rebooted the server, the network connection service experienced errors. We had to take the server down and reboot it to the mirrored disk we made prior to the version 10.1 upgrade. The vendor that is working with us on this project keeps telling me that we should be using DIRT and not Veritas. Is that really the right choice, or is it because they are more familiar with DIRT than the Veritas product. I don't know the answer, but what I am trying to determine is what versions of Veritas are approved for Unity running on a MCS-7835I server?
