We have 1 DAG across 2 AD sites each with 2 E2K16 servers. Site A has FSW. Site B will have a scheduled electric outage (est. 6 hours). I have only done maintenance mode on a per server basis, not server switchover or datacenter switchover. Thinking of using server switchover to move the active databases of both Site B servers to Site A. But I'm confused; the server switchover docs/articles (including Microsoft's) I've read say to just shut down the server(s) after active databases moved using Move-ActiveMailboxDatabase. What about draining transport queues, shutting down cluster nodes, setting database activation policy to blocked, etc.? Don't we still need to run those commands on the Site B servers? (And then reverse them when Site B servers turned back on) We want to control the process as much as possible.
