We are looking into making changes to our BES environment to improve disaster recovery. Currently we have three Domino 4.1 BES sites with each having its own SQL server and database. Geographically, they are located on the East Coast, West Coast and Georgia.
We're considering changing to a single database for each BES to share which would make moving users from BES to BES feasible in the case of an emergency.

What bandwidth / latency do you have between these sites?

1. Can three databases be merged? I've searched and read that dbmerge can combine two databases, but I'm not sure about three.
|
Yes absolutely. 3 = (1 + 1) + 1 ... you merge two and then merge the 3rd.

2. Is it true that the users will not have to reactivate if databases are merged?
|
If you merge according to the
requirements set by RIM, you will not have to reactivate

3. Realistically, what will the performance of the West Coast and Georgia BES be if the single database is on the East Coast?
|
It depends on the performance / latency. If you have < 85 ms RTT from each site to SQL, and you
install the DBNS per the SQL move documentation you really should be good.
