Your original post – you mentioned “receive connectors”. Is hub transport also 
installed?

I saw this script and planned on running it this evening, sweet!

There is no array, it’s an “old CAS” and new CAS. The story is two different 
people tried to patch/update the current CAS server but were unsuccessful after 
several hours, hence them telling me to just build a new one and slide it into 
place.

Run the script I posted on my blog today. It lists almost everything relevant 
to CAS. Pretty much everything should match on the two servers (except for the 
server names).

Do you have an existing ClientAccessArray? (That information is reported as 
part of Get-ClientAccessServer and Get-ClientAccessArray.)

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?

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 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<http://autodiscover.domain.org>
* Update DNS for for rpc.domain.org<http://rpc.domain.org>
* Remove the "Host A" record from the old client access server in DNS
* run Get-MailboxDatabase -Server ex1.domain.org<http://ex1.domain.org> | 
Set-MailboxDatabase -RpcClientAccessServer ex2.domain.org<http://ex2.domain.org>
* Configure Receive connectors identical to the old CAS box

I’m missing something I’m sure. Anyone have a link that has step-by step?

CAS *must* come first in Exchange 2010.

We've seen issues where if the CAS isn't updated first/at same level it will 
fail to connect to the mailboxes.

I have a three-server Exchange Exchange 2010 environment currently - one
CAS and two mailbox servers. 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?
