Back in August-Sept I attempted to migrate a multisite and ran into problems and started this thread: https://premium.wpmudev.org/forums/topic/what-is-current-status-of-snapshot-migration-capabilities
Since then, I notice that there has been a critical update of Snapshot on 10/24/14 that changelog specifies greater multisite support.
I'm ready to give it another shot. Do you now feel that it has the multisite capabilities? If so, what specific steps should I take?
