Thought I’d share this in case there are people who are unaware or have been pending off the migration process.

Starting September 19, 2023, at 11:00 am EST/17:00 pm CEST, unmigrated Mojang accounts will not be able to sign in to Minecraft.net or the Minecraft Launcher to migrate. We’re doing this to ensure that everyone is playing using accounts with improved security and player safety.

What will happen to unmigrated accounts?

Once the deadline for migration is reached, players will no longer be able to access unmigrated accounts. All unmigrated accounts will be deleted at a future date.

What if you don’t have access to the email address associated with your Mojang account, or have any other queries?

The details are unclear. The Minecraft help center link says “Minecraft player support will no longer be able to help with migration-related issues after September 5, 2023.” whereas the minecraft.net article states “[…] starting September 19, 2023, Minecraft Support will no longer be able to assist in any MSA migration-related tickets.”

What do you get for migrating to a Microsoft account?

Microsoft claims improved account security, and 2FA. You will get a Migrator cape and access to Minecraft for Windows (Bedrock Edition) on the Microsoft account chosen at the time of migration.

      If you purchased or redeemed a code for Minecraft for Windows 10 Edition in the past, your Microsoft account is eligible to get Minecraft: Java Edition for free. If you log into the Minecraft Launcher with your Microsoft, it should prompt you to set up a Java Edition username (separate from your Xbox Gamertag).

      More information can be found on their help page here.

        Other way around, actually. I bought Minecraft way before Microsoft owned Mojang, but at some point they gave access to the Windows 10 edition for owners of the Java edition. I’ve installed that before, around that time, and I’m just wondering if that was enough to have migrated my account. It’s worrying tho that I tried to login in at minecraft.net and got a access error trying to reach the login page.

          Redeeming that Windows 10 Edition code is separate from migrating to a Microsoft account. The code was just a free perk.

          If you have not migrated your Mojang account yet, you have two options:

          1. Migrate your profile to the same Microsoft account as the one on which you redeemed that Windows 10 Edition code. The benefit of this is that all your PC Minecraft is on one login.
          2. Migrate your profile to a different Microsoft account, allowing you to double dip. You’ll end up with two Microsoft accounts, but also two Minecraft: Java Edition and Minecraft for Windows 10 licenses. It’s free real estate.
