I’ve been put in a very awkward position and I was hoping to get educated by all the fine BlackBerry Gurus in this forum. The BES Administrator has left the company and I have been assigned the task to upgrade our current BES Server from version BES 4.0.x(Yes it is the original version, no service packs, maintenance kits, etc. have ever been applied) to a brand new server and the most current version, BES 4.1.6.
Under the contract with our Software procurement company, we are eligible for the upgrade and I have already downloaded it, version 4.1.6. I was not employed with the company when the server was built and since the BES administrator left on bad terms, I have no documentation that he may have kept to help in my goals. My company currently has 200 BlackBerry Users and I believe the version of the database is SQL Server 8.0.760.
I’ve searched and read many ideas, how-to’s and still can’t come up with a clear plan on what to do. Some people have advised me to do a "phase" upgrade on the old server meaning since I’m on 4.0.x, apply each service pack and maintenance release all the way up to 4.0.7 then upgrade the old server to 4.1.6. After that then do a “Knife-edge” Cutover to the new server. Is this the right and simplest way? Do I have to apply each Service pack and maintenance release or can I go from 4.0.x and just apply the last service pack which is Service Pack 7 maintenance release #3, is it cumulative? Or do I necessarily have to do the phase upgrade, can I just upgrade straight to 4.1.6? I’m so confused. If anyone can shed some light on what I should do, I would be greatly indebted.
