My company is planning an internal move. We have a single current Exchange 2010 server running on Server 2008 R2. It holds all of the Exchange roles. We have purchased new server hardware and want to move Exchagne to that server. Our plan is to setup the server and mimic all the same settings as the old server. Then, we will migrate the mailboxes, replicate PF, etc.
Now, here is my question. I have read on many different wed postings that some users are doing that very thing, but their OUtlook clients are not updating the account information to the new CAS server. My question is this. Assuming I don't want to do a complete uninstall of the CAS role after the mailbox migration, will just taking the old server offline force Outlook to find the new CAS server, and will that switch be made on the fly? Do I have to uninstall CAS on the old server first?
We have a couple of weeks on this, but I want to get it tested before the move. Thanks.
