Mate OSV 2020

Currently hold a 1600 ton Masters, AB Unlimited, RFPNW, STCW, Radar, Medical First Aid Provider, HELM, BRM, ECDIS, Intro DP, Advanced Fire, and GMDSS. I work in the GoM on a 3300 ton OSV and looking into my Mate OSV license. I know the grandfathering stopped March 24th 2018. Has anyone tested for the OSV mate license since then? I am assuming there is a crossover test or just a Stability test? Also what if any tonnage restrictions? Trying to make sense of the lack of information.
