Changing IP address of cPanel account


So I have a VPS2 with a reseller account and a couple of dozen cPanel accounts under that. I've purchased 2 additional IP addresses and set things so new accounts use one of these. I want to move some of the existing cPanel accounts to either of the new IP addresses. Will this be affected by the TTL settings, and if so should I reduce the TTL times as if I was moving the account to a different server?
