As always, thank you all so much! This also means we won't be trying to go from single CAS to CAS array, we'll be sliding a new CAS server in place of the old one.
Is it advised to build a new one with the same name, or is it trivial to point to a new CAS server? I currently have a new Exchange 2010 CAs server built and patched, but itโs not fully ready. If itโs easier to build an identically-named/IP CAS box I can do that too, but it would require more downtime. Here are the steps I can find going to a different CAS server name: * Update DNS Alias for autodiscover.domain.org * Update DNS for for rpc.domain.org * Remove the "Host A" record from the old client access server in DNS * run Get-MailboxDatabase -Server ex1.domain.org | Set-MailboxDatabase -RpcClientAccessServer ex2.domain.org * Configure Receive connectors identical to the old CAS box Iโm missing something Iโm sure. Anyone have a link that has step-by step? Dave From: [email protected] [mailto:[email protected]] On Behalf Of Michael B.

They are all currently at SP2 update0. Without getting into the why I'm asking, is there any risk in brining the mailbox servers to E2010SP3UR7 while leaving the CAS server where it is? It would be a short-term (few days) scenario but my guy says there may be some reasons to not to have them too far off patching levels. Comments? Dave
