By Ibex Farm, do you mean the PCIbex Farm at https://expt.pcibex.net or the original Ibex Farm at https://spellout.net/ibexfarm? PennController comes pre-installed on the former, but not on the latter
In any case, it won’t hurt to install/update to the latest version of PennController. On either farm, just follow the instructions on this page and your project will import PennController 1.8
