Unity migration from 3.1(5) to 4.0(5):
Old VM Unity 3.1(5) with back end Exchange 5.5;
New VM Unity 3.1(5) with back end Exchange 2000, then upgrade to Unity 4.0(5).
When DiRT restore to the fresh clean Unity 3.1(5), many messages in the mailboxes were lost, Used DirtyRestore from the command line as the following:
All the lost messages restored successfully, but I did this in the lab. Does anybody have experience for the DirtyRestore in the production line?
Thanks a lot.
