I have to shutdown my two DAG members at my production site this weekend to replace a controller on my SAN. Should I wait until this is completed before I start my public folder migration from 2007 to 2013 or will it resume automatically after my DAG members are back online? I don’t know exactly how long my migration process is going to take. We have around 74,000 folders and roughly 8 million emails stored in public folders. I still have to generate the csv files and map them to public folder mailboxes, but just wondering about the known maintenance window I have coming up and whether I should just wait.
