Exchange 2007 Transition (and offsite move)
Posted on 2008-10-07
I am building out a series of 64bit, 2003 R2 servers (AD, NAS, Exchange 2007, Web) with the intent of moving them offsite to rented rack space at Verizon's colo facility. I already have a router, switch and separate domain in this location. The idea is to gain continuity by moving our services and nationwide VPN termination offsite to a more secure, reliable power and AC environment. The AD and NAS servers are already built and running on my local domain/subnet, but are not yet moved. I am building these services in an IBM BladeCenter S. The move will require IP changes and some routing configuration local and remote.
My question is, should I wait until after I have already moved AD, and VPN termination to the new facility, before I build the Exchange 2007 server? Then build 2007 in the environment in which it is going to reside, IP, Subnet, etc. Or can I build Exchange 2007 locally, Transition from 2003, move Mailboxes, and decommission Exchange 2003 then 'Forklift" the entire BladeCenter S. AD NAS, Exchange et al.
I do not have a test environment and with email being the company's life's blood, I only have one shot at this.
