I have a non-UM 3.x box and Customer wishes to upgrade to 4.2 and UM. My path is to upgraded 3.x to 4.x then run DiRT on the 4.x database.

Reinstall the OS and Unity (per cisco docs) and integrate w/Exchange and A/D.


1) Can I preserve greetings?

2) Am I better off using BackupExec to backup and then restore and merge using BackupExec or am I better off using ExMerge? (<150 mailboxes)..or..should I just use DiRT

3) Some A/D usernames and exchange aliases will most likely be different. How to handle?
