Currently there are 20 physically dispersed locations. Physical locations are separated by as many as 1300 miles. Between these 20 locations there are an X number of forests and domains. (I believe X is irrelevant) The end goal is to get all 20 locations under one forest/one domain in a centralized management style with a single location being the HQ. (All enterprise applications such as SCCM, Sharepoint, Exchange, etc will be centralized….to a degree)
I am looking at standing up a new forest/domain CONCURRENTLY with existing domain. I would request new subnets (separated by VLAN) for each location starting at the HQ.
SCCM will be rebuilt on new domain and as workstations are ready to be migrated, I would move workstations to new VLAN and use OSD deployments to rebuild and join workstations to new domain.
This is in a very tiny nutshell!!!
