Customer has a Unity 4.x server that is migrating to new hardware 5.x server (Exchange voice messaging configuration - not UM). Customer already as the 4.x server built to match.
I was advised by a TAC engineer sometime back that ExMerge is not supported on boxes with >200 users. (this configuration is 350 users).
Is there another method to do this? Perhaps using 3rd party BackupExec w/Exchange Agent?
The plan is to move the users over then upgrade the new server.
