True or False: When replacing an Exchange 2010 server, I should setup the CAS array and point its "A" record to original Exchange server, before I setup the replacement Exchange server.
If the above is true, does a problem occur when you have to change the CAS array's "A" record to the new server IP?
At what point should I change the CAS Array "A" record?
True or False: On the original Exchange server, I didn't have a CAS array before I deployed mailboxes to internal Outlook clients, The clients Outlook profiles currently point to the Exchange internal name. I will now have to edit the Outlook connection profiles (point them to CAS array hostname) of all Outlook 2010 clients that connect internally, before I decommission the original server.
