I have a project that went from Original Homeworks then was converted to HWI skipped Interactive went from Original to Illumination. However when we did that conversion years ago we reused the keypads that where HWV link In Illumination you where able to choose HWV in QS you can only choose HWI link and buy a license. Be aware the software conversion doesn't take that into consideration. It shows you can reuse those keypads that are on the HWV link. Don't want anyone to price a job thinking they can just buy a license when in fact they need all new keypads.
