vtp modes on 2924M-XL switches

Hello all, I have a pretty simple question about vtp. I have not implemented any VLAN's but I do have many 2900's out in the production network. I have recently found out that most if not all of them are still in vtp "server" mode. I am planning to deploy 2 4006's into the core running vtp v2, a vtp domain name and 1 of those 4006's will be the vtp "server". To get prepared for this addition my question is simple. Should I telnet everywhere on my LAN and change all my 2924's to vtp "client" leaving the domain name alone for now? If I do that will that affect any of my local area traffic? I know it won't bump up the revision number unless I change the domain name, and I don't plan to do that. Here is a sample from one of my 2924's.

You can change them to the client mode or transparent mode without any issues. But before you introduce the new switches, make sure it's config-revision is lesser than the current server
