Re: OOT: Datacentre migration question

i got one more, when it's time for taking a decision about RE-IP or to not
RE-IP keeping the existing subnets/addresses, the network guys will have to
push for RE-IPing in order to 1) make sysadmins really angry because maybe
they've 1000 VM's with windows 2003 server ro re-address...2) you will have
a clean and plain DC infrastructure, summarizable, scalable and easily
manageable (from the network/security standpoint).

have fun!
