2x Exchange 2010 servers in different AD sites
1 on subnet A (colo), 1 on subnet B (office)
Exchange A is the original one and I have added Exchange B to the mix. Everything seems to be okay. I have moved a few old mailboxes, set up the SSL certificate, DNS, etc.
Without adding another server, how do I keep this migration seamless if I do it in stages? It's going to take a long time to move mailboxes from one Exchange to the other, but I want ActiveSync, Outlook Anywhere, OWA, etc to keep working and not have to upset a bunch of users.
I see this
but wondering it is just as easy as
Set-OWAVirtualDirectory -Identity "Contoso\owa (Default Web site)" -CrossSiteRedirectType Silent ?
Do I need to do anything else for Outlook Anywhere or ActiveSync?
Once someone has been redirected to the new server, do they need to update the config on their mobile device(s)?
