Relocate BES server to new office

We are using BES Server Enterprise 4.0 and Exchange 2003 Enterprise. The BES server and the Exchange server are in two seperate offices (different subnets). As we've been getting more and larger mailboxes, the delivery to the BlackBerry's has been getting slower. In the event log on the BES server there are numberous warmings and errors having to do with syncronization issues and droped packets. So, I was going to move the BES server to the same office (same subnet) as the Exchange server in hopes that it may speed up the delivery (or at least the event log will stop getting the warnings and errors).

In preparation to do this, I attempted to check that I could simply change the IP, subnet,  DG, DNS, ... and have it work properly after the move. I can find no documentation that it is this easy (or info on how to do this if it is not)  on the BlackBerry web site or google.

Is this the propery way to move the BES server between offices?  
If not, can you tell me how or point me in the right dirrection?

    Yes you are right. You can do the move like that. The BES makes contact with the Exchange server with a MAPI Profile. If that account does not change, there is no problem.
    Also the BES makes connection to the BlackBerry Configuration Database. If the BlackBerry Configuration Database is on the same machine (MSDE) then there is nothing to do for that also. If you use an remote MS SQL server for the BlackBerry Configuration Database than you need also the connection to the MS SQL Server fro the new location (also not a problem).
    If you have a BlackBerry Router in the DMZ or have a Firewall between the BES and internet, check the Firewall ports... (port 3101 out bounded initiated by the BES bidirectional)

    It is important that a PING from the BES to the Exchange server replays within 20MS.
