=head1 move-domain.pl
Change the owner of a virtual server
This command can be used to move a sub-server from one parent domain to
another, thus changing the administrator who is responsible for it. It can
also be used to convert a parent server into a sub-server under some existing
owner.
In this mode, it takes only two parameters : C<--domain> followed by the domain name
to move, and C<--parent> followed by the domain name of the new parent server.
Naturally the new parent must be different from the old one, and a server
cannot be moved under itself.
This command should be used with care when moving a parent server, as
information that is specific to it such as the password, quotas and bandwidth
limit will be lost. Instead, the settings from the new parent will apply.
The C<move-domain> command can also be used to convert a sub-server into
a top-level server. In this case, you must give the C<--newuser> and
C<--newpass> parameters, which are followed by the username and password for
the new top-level server respectively. The original owner of the domain will
no longer have access to it once the command completes.
