Storage Migration Service - is the cutover automatically read-only or how does it work?

Mika Suhonen Howdy. The amount of time between starting the cutover and how long they could change files is just a few seconds, as the source is disjoined from the domain and rebooted, forever ending access by remote domain users.

I recommend you simply schedule the cutover and tell them that if they keep changing files those changes will not be transferred unless you did so manually, perhaps using robocopy. We've talked about a catchup differential option but it's pretty expensive to re-run in terms of time and until we have an agent for the source computer that can make that efficient, we opt for not making the cutover take extra hours.
