My minecraft Xbox one edition world won’t sync to latest version

Are you talking about a Minecraft world? Also, what version [Xbox one(the old one) or bedrock (the latest one with cross platform)]?. Usually if you're connected to Xbox live, all worlds sync up to the cloud, if you're playing on Minecraft Bedrock edition,
when you click play, there should be an option at the bottom to sync old worlds.

You can't transfer it from the memory stick.

Also, you will need to have the "Minecraft Xbox One Edition" game, not the "Minecraft" (without the "Xbox One Edition" in the name).

To transfer your world to the Minecraft Xbox One Edition, start your Xbox 360 Minecraft, and make sure you have the latest version of it installed by having the Xbox 360 connected online to Xbox Live.

The latest Xbox 360 version has a feature to transfer one world at a time to a transfer slot. Upload your world to that transfer slot, and then move to the Xbox One.

Start Minecraft Xbox One Edition. There you will have the option to import a transferred Xbox 360 game from the transfer slot.

Once the world is imported, you can repeat these steps for other worlds you have on the Xbox 360.

After you transferred all your worlds to the Xbox One Edition, you can start the "Bedrock Engine" Minecraft on the Xbox One, and again transfer your worlds from the Xbox One Edition.

If you don't have the Xbox One Edition, but only the Minecraft for Xbox One, please
contact the official support.

It’s not possible to transfer a world directly from Minecraft Xbox 360 Edition to the new version of Minecraft for Xbox One. To do this, you will need to first transfer the world to Xbox One Edition and then to the new version of Minecraft.

You’ll need to ensure you have the latest update for Minecraft: Xbox 360 Edition by starting the game while connected to Xbox Live. The most recent update contains a feature that allows you to upload one saved world at a time to a save transfer slot. You
can then use the Xbox 360 save download feature on Minecraft: Xbox One Edition to download that world. You’ll need to make sure you download that save to your Xbox One before you can upload a new save using your Xbox 360. You can do this as often as you like,
but you can only transfer one saved world at a time.

You’ll need to ensure you have the latest update to Minecraft by starting the game while connected to Xbox Live. Choose “Play” and navigate down to the bottom, here you will find a button called “Sync Old Worlds”. Select this button and choose the world
you would like to transfer. You can do this as often as you like, but you can only transfer one world at a time.

You can sync worlds from Minecraft: Xbox One Edition to Minecraft for Xbox One (bedrock edition) in game,
but you cannot sync the content across, as far as I know.

Back then when the Xbox One Edition (the Minecraft with the "Xbox One Edition" in the name, not the new "Minecraft" for Xbox One) was released, there was a short time, where you could buy "Minecraft Xbox One Edition" for a reduced price, if you owned the
original Xbox 360 Minecraft digitally.

Xbox 360 Minecraft and Xbox One Edition Minecraft are two different things. Like having a vinyl record of a music album and then having to buy a CD of the same album. Or having a DVD of a movie, and having to pay for the BluRay version of the movie.

However, the Xbox One Edition can't be bought nowadays anymore. Have you had the Xbox One Edition digitally, you would get the "Minecraft" (without the "Xbox One Edition" in the name) for free.

You can however transfer your Xbox 360 worlds to the Xbox One, if you somehow got hold of the "Xbox One Edition" before it was replaced by the new "Minecraft".

To do that, start your Xbox 360 Minecraft and make sure it's on the latest version. Then use the menu entry to upload your world to the online cloud.

Now start up Minecraft Xbox One Edition and import your world.

With your world in the Xbox One Edition, you can then start the "new" Minecraft on the Xbox One, and import your world from the Xbox One Edition to the new Minecraft.
