As far as i know that is all you have to do, maven does not store any special information in the repository. If you do this frequently, you could also use something like rsync to reduce the time and load of this.
And if you have many machines that need basically the same set of jars, consider using some local repository, like for example Artifcatory. You can set it up to work as a transparent cache, plus you can deploy your own artifacts on it.
