Moving BES users to another server


Running BES 4.1.7 on Windows 2003 SP2 server. I have four BES servers in my BES domain, and one of them is experiencing problems. Each BES has about 700 users on there.

BES1 is the server with the issue and I was thinking of moving the users across to BES2 whilst I can fix this, it may have to go offline for a while whilst some hardware is changed.

What's the recommended method to move users to BES2? Just right click > Move users? In groups of how many? And do I need to resend Service Books etc or anything once they have been moved?

Sharing the same configuration database, right? That's it. Select the users, choose Move User, choose the server, and click ok... here it it from BB:

Might be worth distributing the users between the BES servers - that would mean around 900 on each as opposed to 1400 on one and 700 on the other 2?

You don't specify specification, nor whether you have distributed other components onto separate servers.

Thanks guys.

Is there a recommended number of users I should move in one go? For instance, move 100 or so, wait ten mins, then move another 100 and so on?

Also, once the users have been moved to another BES, is there a way to check if they're working?
I agree with RobMobilty on the splitting users between the other...

I'm not sure that there is a "published" number on the move - probably depends on too many site specific variables, like server/network speed, memory, etc..., but I would think some smaller group is more prudent then all of them... I'm usually cautious on these things myself, as it's only a bit extra time... I would probably do one first, make sure it moves ok, then do 25 or so, then 50, etc... to get an idea on how long it is taking... we are still only talking 20-30 minutes, not hours, if it is all working properly...

I would think the best way to know that they are working is to see them connecting on the new servers (and of course, email, etc... going through).
Moving users to another BES will cause a slow sync to occur. This will cause significant traffic and could impact message flow. For BES 4.1 there is a tool to modify the SQL database to move users over to a seperate instance using the same SRP and CALS. However you'd need to set up a 5th server.

Just be aware that the move will cause much traffic especially with 700 uses.
