Hi!
Our organization is in the process of planning/designing our on-premise Exchange 2013 infrastructure. Currently we have an existing Exchange 2010/2007 coexist environment deployed as a resource forest. My question is it possible to deploy the new Exchange 2013 environment in another resource forest? So we would sort of have the following layout:
The reason why we want to create a greenfield environment for the 2013 is because we still need to keep the 2010/2007 environment for restores and litigation reasons. We also just want to start off with a fresh install so we do not break any legacy applications still relaying or utilizing the 2010/2007 forest.
Another question - if the model above is possible. How would GAL sync work? Would we need to do federated trust between the two Exchange organization?
Cheers!
