But, if we have what we have below:

That means that we have the following domain objects:
(1) foo.com
NS ns.foo.com
NS ns.bar.com
NS ns.example.net
(2) bar.com
NS ns.foo.com
NS ns.bar.com
NS ns.example.net
the following nameserver object:
(3) ns.foo.com
A 192.168.1.11
and the following aliases
(4) ns.bar.com
CNAME ns.foo.com
(5) ns.example.net
CNAME ns.foo.com
Sorry for the notation, but I hope you get it...
Ok, now we transfer the domain foo.com to registrar B, and what
happens is that the nameserver object (3) is also transfered.
What happens with object (4) and object (5)? Are they moved aswell?
Is (4) turned into a host object which object (5) points to? Are the
objects keeping their roles, but (1) and (3) are moved from one
registrar to another? Who can change the IP address of ns.bar.com?
Does the IP-address change imply that (4) is switched from an alias
to a host, and then an IP-address is given to that host? How do one
know if (5) then should be an alias to object (3) or object (4)? Can
one have an alias refering to another alias?
:-)
Millions of questions...
