Hi what will happened to Settlers Runes once they migrate ??

hey i just watched the new league video, since i do use standard... often..
should i get rid of the runes(settlers) that craft enchantment?
or they will turn into the standard new mechanic by it's own??

i mean should i sell them or keep ?

All existing Runes will be deleted. Runecrafts on existing items will remain.
