I've got a 5-server NW 6 Tree: Root Server, ZFD, and 3-cluster nodes.

During initial install, I installed iFolder 1.x (from NW6wSP2 CD) on
all 5,
and, plan was to set it up on the cluster by moving the files. Now
that I
have iFolder 2.1, should I continue and setup 1.x, then upgrade it,
should I just install 2.1 straight to the 5 servers and cluster it?
