Sorry I forgot to update this part.  We need to use migrate-pause in
this version to explicitly pause the migration.  If on source:

  { "execute": "migrate-pause" }

If on destination, don't forget to run with OOB:

  { "execute": "migrate-pause", "id": "pause-cmd",
    "control": { "run-oob": true } }
