Migrating data from R3 to R4 without making a backup

[Jean-Philippe Ouellet]

Hello,

I've written a script [1] to import VMs directly from a Qubes R3 hard
drive into a Qubes R4 machine without needing to make a backup first.

I would definitely recommend making a full backup on R3 and restore on
R4 instead of using this. I just figured I'd share in case anybody
else is unable to make a backup for whatever reason (e.g. [2]) but
really must migrate data anyway.

Unfortunately the script is a mess and probably difficult to audit. I
didn't have time to write something nice suitable for upstreaming, I
just had to get my data migrated. Of course, you should never run
giant messes of code in dom0 that you get from random people on the
mailing list (including me)! If it breaks you get to keep both pieces
;)

Cheers,
Jean-Philippe
