We are in the process of doing a swing-type migration from Exchange 2003 to Exchange 2010. The current Exchange '03 box is running Blackberry Professional Server (not sure of version). The new Exchange '10 box will be running Blackberry Enterprise Server Express 5.0.2.
Am I correct that I will need to wipe the handsets before they will "talk" to the new server? Is there any way around this? If not do I need to issue the command from the current server it is talking with?
