Migrating BES Server from Exchange 2003 to Exchange 2010
Posted on 2011-02-21
Hi, need some advice on what to do with migrating BES Server ...
Currently we have full BES Server running on Exchange 2003. We will be purchasing a new server and install Exchange 2010 on it but will still keep the Exchange 2003 running on the old server.
Would it be best if I just keep the BES Server running on Exchange 2003? Not all users will be migrating over to Exchange 2010 straight away, probably over weeks maybe months. Would the BES Server still work if I have some users on Exchange 2003 and others on Exchange 2010?
Just need some clarification ... also how much down time would there be? And would I need to reactivate BB devices?
