We are currently in the process of migrating out NetWare 6.5 SP8 boxes to a virtual environment using PortLock Storage Manager. We have successful migrated a number of NetWare servers already. However, when we tried to migrate our BorderManager server using the same approach as the other Netware boxes. The server prompted us with a message stating that there was a problem and to resolve this we need to run MM UPGRADE PARTITIONS. (Note this box is running NetWare 6.5 SP07)

First, what does MM UPGRADE PARTITIONS do?
Second, can this be ran with no down time?
Third, what are the potential problems with running this command?

Thank you,
