How can I Unlink my Microsoft account from my old playstation and link it to my new one?

I need to unlink my PlayStation Network account from my old Microsoft account which I don’t remember, & link it to a new Microsoft account to play Minecraft

You can unlink the psn account however you CANT link a different one.

Note: Once a Microsoft account has been linked to a PlayStation® account, neither the Microsoft account nor the PlayStation™ Network account can be associated with a different account. 

If you choose to unlink accounts, then purchases will be returned to the account which made the purchase. Even after unlinking, Microsoft and PlayStation® accounts can only be re-linked to the original account.

This is coming right from the Minecraft website

I linked my old Microsoft account with my PlayStation account a few years ago and I now don’t have access to the account, I can’t link a new account with my PS account as I don’t know the password and the phone number listed on there is my old one - help would be appreciated

Even if you could unlink the account you wouldnt be able to link a different one.

I was trying to link my Microsoft account onto my new ps4 but it's still connected to my old account

Just be aware even if you can unlink the old Microsoft account you wont be able to link a different one if thats what you are trying to do. It will only ever let you link the original one.
