I need to move Blackberry users from one BES to another and was wondering the best way to do it? Here is the setup. Company A is located in London and I have Company B, splitting away from Company A. I have a new AD Forest for Company B but a cross forest trust is in place to migrate users and exchange mailboxes. Some of these users have blackberry's and there is a BES Server is Company A. I have a brand new BES server is Company B and need to migrate uses from A to B. I know i have to wipe the device but how can i move Blackberry users with minimum impact? is there a tool to move users (configuration/activation) to the new server? Is there a step by step documentation to help me do that?
