Exchange 2003 to 2010 Coexist SAN
Exchange 2003 as primary domain controller
New Exchange 2010 installed with all roles
SAN cert from digicert in hand:
mail.domain.com
autodiscover.domain.com
legacy.domain.com
We currently use a self signed SSL
I have a separate public IP for the Exchange 2010 server
I have an old ISA server but all it is doing is webpage proxy.
I have not made any changes except to look at replication of free+busy to the new server
What I need help with is order of events to coexist from here. I'm thinking:
1 Install the new SAN on Exchange 2010 then export to old 2003
2 Change public DNS to point to the new 2010 IP address (should I assign legacy.domain.com to the current public IP? It is the PDC and it will remain until the Old Exchange 2003 can be rooted out)
I think I'm on the right track but could really use some advice prior to digging any holes for myself
