I have an exchange 2003 box in Texas. I bought a new server running Windows 2008 with Exchange 2013 std, located in a Colo in Irvine CA.
I want to migrate from 2003 to 2013 (Exchange). I'm looking for high level ideas on the BEST way to do this. Migrating up to 500 email accounts.
The old 2003 server is at an office in Texas. The new server is in a colo.
Put them on the cloud temporarily?
setup a VPN between locations and migrate?
Upgrade from 2003 to 2010 first , then 2013?
What about Active Directory?
Why not leave Exchange is Texas and setup HTTPS? (question to myself - no need to address).
