Looking for ideas regarding Server/DNS migration

I have 7 cPanel servers that I'm migrating to 7 new cPanel servers at a different data center. Since I am moving to a new data center, I am unable to keep my IP's. Migrating the accounts etc isn't going to be a problem, however I am looking for ideas on how to best handle DNS.

Each of the 7 servers are currently running their own set of name servers, there is no clustering involved. I am thinking that I could use the same name server hostnames on the new servers than just switch the IPs at the registrar when the accounts are copied over. This would prevent users from having to update their name servers. The only problem I see with this is that propagation will cause data to be at least 24 hours old which may be a problem.

What is the best method to go about this? Is there a better way that I can migrate the servers without causing a problem with outdated files due to propagation?

Thanks in advance!
