We are about to install a second Exchange 2007 server into our organisation. We have 3 sites, and currently have legacy Exchange 2000 servers in all 3 sites, and our new E2k7 server already installed into out local site (Hub, CAS, mailbox roles). We are therefore currently in co-existent mode.
Next stage of our deployment includes:
a. Deployment of Exchange 2007 servers in our other sites
b. Upgrade to Exchange SP1 in our local site
Can we install E2k7 SP1 straight into our remote sites?
Do we need to upgrade to SP1 in our local site before installing E2k7 SP1 in our remote sites?
As Im concerned about how mail will be routed between site, can you point me to a reference specifically to research installing a second E2k7 server?
I need to implement a DR strategy for both can you point me to a reference?
