I have seen many posts that reference the same query but couldnt find a clear-cut answer or way forward.

We have SQL mirroring in place (without witness), all works fine (failover etc.)

But in a scenario where an upgrade is done on the DB, do we have to break the mirror, upgrade active node/db, backup the DB, restore full to mirror DB and recreate the Mirror ? Or as the RIM guide says (http://www.blackberryforums.com/bes-...-0-sp2-ha.html) or mentioned in other posts, upgrade Active node/DB, failover and upgrade the other Node ?

Personally I feel the RIM option may not work and the 1st option is the safest, but what interested to know what others have tried and tested ?
