A company wants to upgrade their environment to exchange 2010. They have an existing 2007 environment.
They have ESX vmware platform and want to go ahead and build out two front end CAS/HUB servers and a temporary backend mailbox server.
Their requirement is that their production mailboxes be moved (migrated) to a hardware 2 server DAG solution, but they are not ready to purchase hardware until 1st quarter 2013.
So, the proposed solution is to build out 2 FE's and 1 backend mailbox server in vmware now and get coexistance running , confirmed, tested, test moving mailboxes, mailflow, etc.
Once that is complete and they purchase the two mailbox servers, we'll add them in, create the DAG, and then remove the temporary mailbox server.
Do you see any flaws with this, or something I'm not aware of?
I know I'll need to move the OAB generating role to one of the new DAG members from the temporary mbx server befiore I decommission it. Anything else that would need to be done or that would impact the environment?
thanks!
Josh
