I have a series of questions because I am still new to Exchange and inherited a horrible 2010 environment. We currently have a single Exchange 2010 SP3 running all the roles. There are no quota on the mailboxes and very few securities in place.
At this time there is not any available windows for offline maintenance but we want to shrink the mailbox DB. Could I setup an Archive Mailbox Server, set archive policies, and have the data automatically archive from the Mailbox DBs to the new Archive DB that I plan to be on a different server? Can the new Archive Server be a new Exchange build that is only used for Archiving?
Later, I would like to move to a DAG solution. Could I take the configuration of the current Exchange server and proposed Archive server and migrate to a DAG solution? Would I just need to migrate the roles off the current server (i.e. Mailbox role) to two Active/Passive new builds and role back the current to a CAS/Transport server?
Any direction would be appreciated noting currently we need to shrink the Mailbox DB and still remain online and provide users with all past emails. PST is not a very good option, that is why I think the Personal Archive may work.
Thank you all in advance
