yeah, i learned the SRP violation the hard way too.
however, with turning up the standby server, i will have to likely be making a call to RIM again to have them clear it (i do not think its possible to go through a complete installation and full updates w/o having the BES online at some point during the process).
a few questions (if you know)...
how often do you backup the database and blackberry service account mailboxes?
on the server instances, say if ours is ICWPBES11 for the current production server, does that have to carry over to the standby server as well - or can it be named like ICWPBES21 (server name, instance one) and have no affect on the users? or is the only info that matters are the SRP Identifier and Auth Key?
