We are currently putting together the project plan to update our exchange environment from 2003 to 2007. Currently for our DR scenario we have an EVS (cluster) at our main Datacenter and a passive cluster at our DR Datacenter. We use Netapp to take snapshots and ship them to the DR site. The EVS is brought up for the test and then destroyed before bringing the link back up between the sites.
For 2007 we are looking at using the SCC to SCR model for DR. We would ship the logs to our DR site and bring up the server that way. But I cannot find any documentation on how to then ship that data back to the main Datacenter or what the tear down steps would be before bringing the link back up. I can find lots of documentation on how to bring the DR site up with various techniques but I cannot find what to do when we want to bring the main site up and either destroy the DR test information (what we do now) or ship the information back to the main site (what we want to do).
