My client is running exch 2003 now with a BES server version 4.1.xx something. We have now installed an exch 2010 server which we will be migrating the users over to. My question is, what do I need to do to the BES server to get the users to be able to get their email on their Blackberries once they are migrated over to exch 2010?
Do I need to do anything to the blackberry devices if there is nothing needed on the xch 2010 server?
Any help would be great along with the steps needed to be completed.
