We are going to migrate the unity to another server in the following:
1. DIfferent name and ip
2. Different AD and Exchange Orgnization
3. AD and exchange has no any user and mailbox.
Just double check with you as long as i installed a clean and ready unity server into this new enviroment though with different name/ip/ad/exchange, restore should still work, it should create user and mailbox on the fly,
Unity 403, exchange 2k off box
