We're going to replace an existing CAS with a new one. The new server will utilize the same IP as the old one, but it will have a different name. There will be no CAS array, even one with only a single server in it.
Outside of updating the RPCClientAccess server attribute on the mailbox databases, are there any other changes that are required to facilitate the switch? The old server will be retired after we validate the new one is working, so we're intending on letting autodiscover find the new CAS for existing mail profiles after the existing one is removed.
Any feedback is appreciated. :)
