Oca is cold sensitive. I would lift them out, pop them in a paper bag and store some where cool and dark ready to plant out in spring.
Some of the ones I planted overwintered in their bed (I thought I had them all!) and re-grew the next year. However we don't usually get really bad frosts here in N.Ireland. I doubt they'll have survived winter past.
I was disappointed with their harvest though. Small and fiddly. And kids weren't so keen on them. So I've stopped growing them. Spuds do much better here!
