=head1 clone-domain.pl
Duplicates an existing virtual server with a new name.
This command will duplicate an existing virtual server with a new
domain name. Any web content, DNS records, mailboxes, mail aliases, databases
and other settings associated with the original domain will be duplicated,
where possible.
The virtual server to clone is selected with the C<--domain> flag, and the
new name is set with the C<--newdomain> parameter. When cloning a top-level
server the C<--newuser> and C<--newpass> flags can be used to set the login
and password of the new user that will be created as part of the cloning
process.
If the cloned virtual server has a private IP address, Virtualmin will allocate
a new IP for the clone from the configured IP allocation range. If no ranges
are defined or you want to use a specific address, the C<--ip> flag can
be given instead, followed by the address for the new domain to use.
The cloning process will copy any databases associated with the original
domain under new names, and duplicate their contents. However, it will NOT
update any scripts installed into the original domain that are configured to
use the original databases - this must be done manually.
