currently we are running BES 3.6 on exchange 2003 with 134 users. we are going to install BES 4.0 on a new server with a temp SRP. how can i migrate the users across to the new server and finally moving the SRP from BES 3.6 to the new BES 4.0. The users cant be offline for long. without having to move them from BES 3.6 to BES 4.0 - there device will need new encryption key and when i move the SRP all users will need new encryption keys again which will annoy the users and will be difficult to get everyone up and running quickly. any easy solutions!
