E-mail addresses are not that much of a problem. We have the same with
departments (we use user@department.utwente.nl) who change names or
merge with other departments. Mail-servers can handle multiple domains
perfectly.

For some departments merging or changing we make CNAME from the old
names pointing to the new names.

We have had the experience.

At one time you better change everything from one name to the other and
make arrangements for the old name.
Last week we renumbered all of the computers at our university. It took
us half a year of preparation. We took the opertunity to force all
systems on DHCP (static addresses at firts) including new servers for
DHCP, radius and DNS. So we could build and test the complete
namingscheme before we activated it. Besides IP-adresses also all
gatewayaddresses and netmasks changed. Those were the things the most
problems arose. Systems accepting the new IP-addresses but not the new
netmask and/or gateway.
And also some Microsoft exchange servers didn't like the change very
wel. But we are customed to that. Every change seems to give problems
with those systems.
