Steps done today on the new CAS: Change the Autodiscover URL in the Service Connection Point
Modified the InternalUrl and External attributes of the EWS Modified the InternalUrl attribute for Web-based Offline Address Book distribution Doing queries of Get-ClientAccessServer, Get-WebServicesVirtualDirectory, and Get-OABVirtualDirectory I see the new CAS now has the same entries as the current CAS (https://webmail.ochin.org in front of those services now). As near as I can tell, doing the steps I have listed below and doing a VIP swap at our firewall are all that remain to being the new box into production. MX record will remain the same as we have Spam Titan’s in front of our Exchange boxes. Tests to verify would be OWA login, ActiveSync login, and Outlook client login (and confirm mail traffic each direction). Anything jump out at anyone as to what I’m missing? The Set-MailboxDatabse command is what will point the mailbox servers at the new CAS, correct?

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 it’s not fully ready. If it’s 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 I’m missing something I’m sure.

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
