Why is my son's minecraft preview worlds not syncing from his Xbox one to his new Xbox...

Hello Roberto R, my name is Oskayra, and I will be happy to help you.

Beforehand, it is important that you keep in mind that this is a public community forum, so we are players like you, we are not employees of Microsoft or Xbox, so we do not have access to any user account or check anything from the forum. All users help each other with common problems.

Remember that this is a possible solution, if it doesn't work for you we can try another one.

Note: This is a public forum therefore, I suggest you not share your personal information.

I am very sorry for the problem you are going through, with the intention of being able to help you I did an internal search on the Microsoft forum and found a publication by Gerardo C., an independent advisor, where he suggests the following steps that you should follow:

Please try to solve the problem as follows:

1. In your console settings, go to the "Account" section and select the "Delete accounts" option and choose the account in question. This will delete your profile from the console but you will not lose any of its data, don't worry. .

2. With the Xbox on, press the power button on the front of the console for 10 seconds until it turns off completely (keep your finger on the button even if the light has gone out before the 10 seconds are up, until the time is up). ).

3. Unplug the power cord from the console and wait 30 seconds.

4. Reconnect the power cable to your console and turn it on normally.

5. Then add the account back to your console so that all your profile information is downloaded again, it won't take long. This also helps synchronize the licenses of your account in the console.

6. Check if the problem persists.

Sincerely,
Oskayra.

Although it is possible to sync worlds from Bedrock to Minecraft Preview, there's no way to transfer the world from Minecraft preview to your Minecraft Bedrock Edition as Previews are only beta

Hope it helps, if you have further questions feel free to ask, greetings from another Microsoft user

Hi there Trent welcome to the community forum! Christopher here, an Xbox fan and been on Xbox for years already. I would really love to make your day by helping you out. We can try resyncing your worlds! To sync your worlds from the Xbox One Edition to Minecraft:

Sign into your console with the account that you previously saved your Xbox One Edition world with.

Launch Minecraft and select Play from the main menu.

On the Worlds tab, select Sync Old Worlds if your existing games haven’t already been migrated.

Select the world that you want to migrate and wait for conversion to complete.

Your world will now sync to the new Minecraft when you sign in.

In addition to world sync, certain skin pack, texture pack, and mash-up pack purchases that you made on the console will also be available when you play the new Minecraft, and on your other devices

When you play the new Minecraft on your Xbox One console, you’ll will be able to sync your existing worlds from the Xbox One Edition. Additionally, if you have a Realms subscription then your realms will
also appear on your Windows 10, iOS, Android, Kindle, or Gear VR devices (if you own them).
