Question here... I know a CAS really isn't needed unless you are going to have a ton of nodes. But what about this scenario:
LegacyForest A
LegacyForest B
NewForest C
Both LegacyForest A and B have their own SCCM 2007 deployments. We are looking to install a new 2012 deployment into Forest C and migrate everything into that. Before we can get all machines and such migrated into the new forest we want to manage both the the legacy and new forests with the 2012 deployment. Would it be better to install a Primary Site server into NewForest C then have it manage the Legacy forests with DPs or would it be better to run a CAS in NewForest C with primary site servers at in each LegacyForest? As a note we have 2 way trusts between LegacyForest A and NewForest C as well as with NewForest C and LegacyForest B.
Thanks!
