Migrating a BlackBerry Cross-Forest: Well Done RIM!

I am currently working on a Cross-Forest Exchange migration where we have to also migrate the BlackBerries. In the past you needed to wipe the blackberries and use enterprise activation to activate them on the new server. If the blackberries had some apps deployed by organization, this was a huge issue from the logistic point of view, since in a lot of cases the applications were installed by hand by the IT department before the blackberry was given to the user.

So now you can use the BlackBerry Enterprise Migrator (I think that is how the tool is called). You do need to have both source and target BES servers on version 5. But the tool does real wonders. We just tested a migration of a fully equipped BlackBerry complete with some custom apps on it. The user experience is extremely smooth. It tales about 15-20 minutes, and during the move the BB does not receive any mails, but all the existing messages are there. then once it switches all the user gets to see is “Your Device is activated on a Blackberry Server” message, which you can just dismiss with an “OK”. You do not even need to restart the device…

All I can say: WELL Done RIM!!!


  1. It is not supposed to be possible to move users to a new Exchange Org. All else is possible and supported by BlackBerry support except a new Exchange Org.

  2. Well it worked Cross-Forest. I saw this when working on a cross-forest Exchange 2007 migration

  3. Can you please provide the steps involved in performing this migration using the Blackberry migration tool kit. Because I cannot find any link on explaining how to use this tool for cross-forest migration.

  4. Unfortunately I do not have any documentation, as I was just watching the guys doing it. All I know that you need full access to both Source and target BES servers and the SQL databases.
