There's no need to have the .builder files on the servers in the Swift cluster. All you need are the .ring.gz files. In my experience, most clusters do the ring modifications offline on a separate server and then deploy the .ring.gz files to the servers in the cluster.

It sounds like the process you first went through is right.
