Can I kasher my pot?

Question

Lichvod Ha Rav Abadi, I cut an onion (davar charif) with a Dairy knife. I thn cooked the onions in a clean (hadn't been used for all of Pesach), Meat metal pot with hot oil. Can I kasher the pot? I may have stirred the contents with the dairy metal knife with wooden handle- I'm not 100% sure if I did, can I kasher it? Thank you for your time
