I have a single exchange 2003 server that I want to migrate to exchange 2010.
My exchange 2010 setup consists of four servers. Two CAS/HUB servers setup in a CAS Array, and two Mailbox servers with a DAG configured. The servers are just installed, I haven't started the migration yet.
I am reading many articles on what I have to do before I start the migration. Like what I have to do for both the exchange 2003 server and the exchange 2010 servers to coexist in the same organization. This part is confusing me. Currently my OWA URL for exchange 2003 is:
" (NOT USING SSL)
My active sync is: "server.domain.com" for my exchange 2003 server (NOT USING SSL)
For Exchange 2010 my CAS array name is mail.domain.com. Can I use this name for OWA also so it is redundant. Also, my URL for OWA and Active Sync on exchange 2010 is "https" (USING SSL) and exchange 2003 is not. Do I need to buy a certificate for the exchange 2010 CAS Array before I start the migration. I've read a lot of articles, but I'm a little confused and hoping someone can explain this in a way I can understand. Thanks.
