How do I merge my old Java account with my new Microsoft account?

Hello Mr_Pigersus, My name is oskayra and it will be a pleasure to help you.

I tell you in advance so that there are no misunderstandings, this is a public forum for user-to-user support. We are users who help other users. We do not work for Microsoft and do not have access to any user accounts.

Yes, you may be able to recover your old Minecraft Java edition data. According to the information I have found, Microsoft still retains data for Minecraft accounts that were not migrated before the deadline.

To recover your data, you can contact Microsoft support. They will be able to help you verify ownership of your old account and potentially restore your data.

When you contact support, make sure you have the following information ready:

The email address associated with your old Minecraft account

The username of your previous Minecraft account

Any other information you may provide about your previous account, such as purchase history or game history

Once you've provided this information, Microsoft Support will be able to verify ownership of your account and potentially restore your data.

is my Java name and GarnFlieger7910 is my Bedrock name.
I did merge my Microsoft and Mojang accounts.

I have the same problem. Purchased Java version a long time ago, and Xbox more recently. Now I can't migrate my mature Java account. They need to implement a mechanism by which accounts may be merged. Completely insecure and unacceptable to ask users to create new Microsoft accounts just to play Minecraft.

I have 2 xbox accounts and I was wondering if I can merge my old Xbox account to my new Xbox account?

No. Unfortunately accounts cannot be merged and nothing is transferrable between accounts
