Going from Blackberry Enterprise 4.1 to Blackberry Enterprise Express 5.0.2 looks like a daunting task, but really it is not that tough.
So there I was, ready to find the stash of nukes I hid somewhere. In anticipation of the migration from Exchange 2007 to Exchange 2010 coming up real soon, I had to upgrade our BES (Blackberry Enterprise Server) to the most recent version. the prior guy who had gone through 2 weeks of Blackberry training kept putting it off, coming up with excuses, and now is no longer with the company. I had done what anyone should do. I read up on the product and learned how to do the upgrade. Then the worst thing happened. Upon running Windows Update and Rebooting, the Blackberry Server came up but only enough to be pingable. I couldn’t remote into it, which meant so much for doing everything after hours.
First thing in the morning I went to our server room at the office where the BES is located, forced a hard reboot and the server came up normally. then came the task at hand. Few small things about going from BES 4.1 to BES Express 5.0.2. First you have to completely uninstall 4.1. Second, 5.0.2 is extremely slick. Once installed, and I got the users added into it, the majority of phones were found and automatically connected, as if they had always been on the 5.0.2 version of the BES. There were a couple of problem phones, but for the most part, all the planning on having to reactivate 50 Blackberrys went to the trash.
Sometimes, when things get done right, good surprises happen. Just never let it stop you from planning for the worst case scenario. Next step will be the final Exchange Migration.
