need help with the following scenario: All users and servers are currently at SiteA. We have created a remote site (SiteB) and installed Exchange servers at this new site. We now have to migrate all mailboxes to the new site while users will still be located at siteA.
My concern: Is there any configuration I need to be aware of, particularly CAS before we start migrating user mailboxes to the new site. I am concerned about autodiscover, DNS, internal and external URL's.
Thanks for your guidance.
