[Users] prlctl migrate on vz7 fail

[Jehan Procaccia]

Hello

I finally found a way to use prlctl  migrate
is was only a pb of firewall !
as soon as I opened the firewall on the destination hosts it worked fine .
However I would like to know which ports a necessary , for now I openned 
whole scope from 0 to 65535 on the destatition server
but I would rather open only necessary ports .

Thanks .
