Unlinking playstation account and adding a different 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

It tells me to go to my previously connected Microsoft account

I assume this is for Minecraft on Playstation? If so then per https://help.minecraft.net/hc/en-us/articles/360037725571-Minecraft-for-PlayStation-FAQ

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.

So you can totally unlink the Microsoft account but you wont ever be able to link a different one.

This is a sony restriction. Not a Microsoft/Xbox restriction.

I don’t know what email I used to link to my PS5 for Minecraft account. Could somebody unlink the account connected to my minecraft account if not can you tell me what email is linked to my minecraft account. Would I have to go to PlayStation to get it unlinked or do I go to Microsoft since it’s the accounts that are needed.

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

According to this thread you can unlink the accounts: Minecraft PS4: Unlinking Microsoft Account - Microsoft Community

However, even if you unlink it, according to Mojang you can only Re-link it to the original account, you cannot link a different PlayStation account to the Microsoft account.

Thank you,
