Data will be copyed to the other pool. The original data will stay until
the volume is purged, but in the database, the location of the files
will be changed to the new position (pool, volume).
Restore will be done from the new location after the migration is
completed. The original job will marked as migrated (jobstatus "M"). If
you want to use the original job for restore, i think it could be
possible to import and reindex the job with bscan.
