We are currently in the progress of migrating from Novel Groupwise to MS Exchange. I spoke to a tech at RIM and he told me that the only way to migrate our BES users is to get a temp SRP ID, setup a Exchange BES, delete users from the Groupwise BES, wipe the device, and reactivate them on the Exchange BES. This pose a few problems. First we have about 200 users. I can't imagine what it would be like to manually backup and wipe 200 devices. This would require us collecting the devices and that brings us into problem two. We are planning to have the cut over happened during a weekend. I'm sure the users will be hard pressed on giving up their phones and will come after us with pitch forks if we force them to hand it over.
Ultimately we want to be able to do the move with minimal down t time and changes to device settings. From your experiences, what is the best way to approach this? Thanks in advance for any inputs.
