This weekend ill be introducing a 2012 R2 DC to a domain and forest 2003 functional level.
We want to have a roll back plan incase something goes pear shaped. We have already done all the pre-reqs and have taken a system state backup and C drive backup of 1 domain controller but want a more full backup of all DC's.
So we want to VEEAM backup and replicate our current 5 domain controllers from our data centre (where they are all located) to head office. So the idea is, we start replicating now so the bulk of the replication comes across and just before we introduce the new DC, we will do another replication to get the replica as up to date as possible.
If something goes wrong, we power on these replicates and power off the prod ones and things should just work like before right?
Any advise is appreciated and steps to do this VEEAM backup and replication.
