Hi, What would happen if you move Exchange 2007 SP1 MB, HT and CAS from site A to site B and power it on? :-) Has anyone tried that? Any articles or docs you can recommend? Many thanks. Pawel

I would probably change an ip address ;-) Thanks for reminding. So you say that HT&MB&CAS server would get aware of a new site [using SRV records?] and would start routing emails [HT] using AD replication? HT routes emails to another HT server and then to a smart host. I'm aware of changes in regards to CAS server: dns, firewall, ... Thank you. Pawel

Guys, Many thanks for your help. Regards, Pawel
