If you are simply moving repository from one machine to another (and
keeping the same path), you could set up port redirection/forwarding on
the old machine, so all incoming connections on the old pserver box are
transparantly forwarded to the new pserver box.  This can be achieved by
redir(1) [it's available on Linux]. Or if you use xinetd i *believe* it
can do port forwarding too (haven't tried, YMMV).

This should allow developers to use either CVSROOT and remove the need
for a "sudden" switch.  The downside is that there bound to be somebody
who "forgets" to switch, which you will only discover once the port
forwarding is switched off.

On a related note: If you're moving the repository across machines, how
do you identify the machines?  If you have control over your DNS set-up,
you may just want to use:
[substitute as appropriate]
and let "pserver" be a canonical name for the real box.  In this way,
you can move the repository to your hearts content provided that you
update DNS accordingly (and keep the same path within the box).
