Hopefully someone can advise......

I shall be performing an upgrade of our BES server to 4.1.4 and need to provide a backout plan in case anything goes wrong!!

The environment - MS Exchange 2003
2 BES Servers (both running 4.0) - all users migrated to the new server, currently using a temp SRPD, both connected to the same SQL database

The plan is to do a 'in place' install of BES 4.1.4 on the server with the temp SRPD, then un-instal BESl and decomission the 'original' BES server ...assuming all goes well.....

Has anyone performed such an upgrade, backout plans that coulsd be advised of if there is a problem??

Many thanks
