No, simple installation originally with a single controller. At some point I added two rack controllers. The rack controller update to 3.4 went fine, but the update on the main instance failed. The main one is the one that goes back to 1.6 or 1.8, or possibly at some point got reinstalled with 1.9. But definitely the 1.X series. The rack controllers were added later in the 2.X or 3.X series.
