Testing Potential Shadow Migration

1. Configure the source so that the ZFSSA has root access to the share. This typically involves adding an NFS host-based exception, or setting the anonymous user mapping (the latter having more significant security implications).
2. Create a share on the local filesystem with the shadow attribute set to 'nfs://<host>/<snapshotpath>' in the CLI or just '<host>/<snapshotpath>' in the BUI (with the protocol selected as 'NFS'). The snapshot should be read-only copy of the source. If no snapshots are available, a read-write source can be used, but may result in undefined errors.
3. Validate that file contents and identity mapping is correctly preserved by traversing the file structure.
4. If the data source is read-only (as with a snapshot), let the migration complete and verify that there were no errors in the transfer.
