If the controller migrate the level w/o any data lost will be great - I will do additional partition afterwards. I will send update. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (FreeBSD) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkgcgMMACgkQibJkIG65HMdj3ACdGAX6fOww6UAvWp6sDdCGG3P4 oa0AoIDkcpzVvqNDBe60ODXKjH/32aWR =D/Et -----END PGP SIGNATURE-----
