a memory device; and
a memory sub-system controller, operatively coupled with the memory device, and configured to perform operations comprising:
determining to perform a hot-cold swap based on a minimum write count value of first write count values for a first set of mapped management groups exceeds, by more than a predetermined offset, a minimum write count value of second write count values for a second set of unmapped management groups;
in response to the determining to perform the hot-cold swap, selecting a first management group of the first set and a second management group of the second set for a swap operation; and
