running servers parallel

I'm going to undertake a hardware refresh soon and I was wondering if it is possible to run two machines (X and Y) with the same hostname (but different IP addresses) on the same network? Server X is the original server and has an entry in DNS. Server Y is the new server and won't have an entry in DNS until server X is taken offline.

You can do it alright, the other hosts on the network are going to be using their own /etc/hosts or your DNS for figuring out which IP address the name resolves to. Possibly the host which thinks it's the other host could be mildly confused, but then who amongst us isn't (-:
