Not sure what retraining would be needed the drill is the same as for the NG and as I understand the fix will compare the two AOAs and if a disagreement is sensed the MCAS will only trim forward for 2.5secs not 10 seconds as it was programmed to do.
Some countries are requiring simulator training before the MAX is allowed to fly in their airspace.
