we are in process of migrating from exchange 2007 to exchange 2013
we have resource forest setup . In this kind of setup, we have Exchange sits in another forest (domain.lan)and AD account in another forest. (domain.com. Between both forest, we have tool like MIM, which replicates the data from primary AD forest to Exchange forest. MIM creates ID in Exchange forest as disabled.
Finally, linked mailboxes are setup in primary forest. This way user access their mailbox
1) we have AD(having all fsmo roles) on our exchange CAS server (exchange 2007) .we have only 1 CAS server.
while migrating to exchange 2013, how can we take care of AD as we don't want DC again sitting on exchange 2013
2) can we convert linked mailboxes to user mailboxes , in this scenario , how can I restructure AD as we have disabled AD accounts on exchange 2007 and another AD in another forest.
3) we have other sites like NY, CHICAGO, FLORIA but these sites have their own DC and have their own domain names like florida.lan, Chicago.lan. we want to consolidate all these dc in location. we have corporate office which is having domain.com as DC name
can we club them under 1 forest
