I've got a CentOS 4.3 distribution in nfs mount.
Put 4.4 on the nfs mount. Create a local yum repository for your machines from which to update, and change your CentOS-Base.repo file to point to the new local repo for base and updates packages as well as whatever else you choose to mirror. Dag's yam tool is excellent for this, though rsync or lftp's mirror function work quite well also.
I believe you mean mrepo, not yam. http://dag.wieers.com/home-made/mrepo/
GET IT RIGHT!
And yes, it is excellent for this.
