We are actually do an upgrade in place.
We have the SQL database on our 4.1 BES, so we are going to copy it off and put it on a new box.
Then we are going to install 5.0 on a new box and name it the same as the 4.1. We are then going to point the 5.0 to the copied SQL database and turn off 4.1 and turn up the services on the 5.0. This makes the SQL database think we just did an upgrade to the existing server. You must ensure your incident name is EXACTLY the same as the current BES.
The reason we are doing it this way instead of using the transport too is this: We have over 600 4.3.x devices. 4.3.x is not compatible with the transport tool. RIM recommends that the either be 4.2.x or 4.5 and higher to use the transport tool. The 4.3.x software cannot handle having two policy's on it which is what happens when you use the transport tool. Once you pull the user off your 4.x server, the 4.x policy deletes itself.
By doing the upgrade this way we basically are tricking the database into thinking we upgraded in place no need for two policy's, no transport tool, etc. Also saves us about 800 man hours in doing upgrades or reactivations. In order to reactivate a 4.3 device on 5.0 you will need to wipe and reactivate, if your going to have to touch it, upgrade it to 4.5 so you have the ability to push out new OS's via OTA. Also if something happens we turn off 5.0 and simply restart 4.1, so we have a fail safe.
We are going to be doing this in the next month or so, so stay tuned!
