I purchased a membership specifically for the snapshot plugin. I sent a pre sales question to confirm that snapshot would, in fact, be capable of moving a single blog from one multisite network to another. Your team member said that it would definitely handle that. But it doesn't seem to be working.
I installed the plugin in both multisite installations. I made a snapshot of a single blog in multisite A, created a blog with the same name in multisite B. I then attemped to run the restore, but all I'm getting is "Archives: pending".
