2003 R2 to 2012 Migration?
I currently have a two server setup on one domain. PDC and SDC that DFS replicate to each other.
My idea was to pass all the GC and roles to the SDC - wipe the PDC and fresh install 2012 with some minor HW upgrades to the server.
My issue comes when deciding where to go from there, do I add the 2012 to the domain and promote it taking over the PDC role again?
Can I have the 2012 functionality with a 2003 SDC or will I have to strip its roles?
I will eventually be virtualising the SDC then going through the same process on the other server hardware to remove 2003 from the domain, this way I get no downtime.
Any ideas would be welcome.
