Link Minecraft Java account to Microsoft account?

I have a question about Minecraft and it is so that you will need a Microsoft account from November 24th, so I wanted to ask you if there's a possibility to link your Mojang account with your Microsoft account?

How do you get on the narrow board, only new registrations need a Microsoft account, no existing Mojang accounts. If you have already bought Minecraft and play it, you will receive an email from Mojang from January 2021, explaining how you can migrate your Mojang account to a Microsoft account.

Until then, you can continue to play as normal. Anything else would probably cost you your premium account. So wait until you get an email.
