You can simply change the version from 9.0.1 to 9.1 and it will run fine. The only changes from 9.0 (or 9.0.1) to 9.1 were in ZoneHVAC:EquipmentList and HybridModel:Zone. Since these files do not include those objects (at least the one I tested), you can simply change the version number in the IDF file and run it in 9.1.
The reason why the IDFVersionUpdater gives you an error is because it doesn't have the transition file to go from 9.0.1 to 9.1, because 9.0.1 was a minor update to 9.0, and no additional transition file was created. If you change the version object from 9.0.1 to 9.0, the IDFVersionUpdater to v9.1 works fine.
