New Minecraft Disables Me From Playing Xbox One Edition

You can only transfer your world from Minecraft 360 Edition to Minecraft One Edition to (new) Minecraft.

Which Minecraft version do you use? For example, Minecraft 360 Edition in (new) Minecraft is not possible.

Only Minecraft 360 Edition to Minecraft One Edition and Minecraft One Edition to
(new) Minecraft

Minecraft 360 Edition and Minecraft One Edition are out of support and now the Legacy Editions. New Minecraft is the Bedrock Edition

The older Minecraft: Xbox One Edition is no longer supported with new features and will not be receiving any updates or new DLC in the future, but you can continue to play Minecraft: Xbox One Edition if you wish.

Hi there,

Have you hard reset your Xbox and power cycled it to see if Minecraft on Xbox One received an update as well?

I noticed this note on the Mojang support page for transferring worlds on Xbox Consoles: "Please note:
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."

If I'm not mistaken Minecraft Xbox One Edition was upgraded to the new version of Minecraft with the BTU but based on that note you would have to upload the worlds to the Xbox One edition and then to the newest version of Minecraft on Xbox One. I'm not sure
if this has anything to do with the issue but I figured it was worth noting.

Yes, both my Xbox 360 and Xbox One are fully updated. Minecraft Xbox One Edition or Legacy Edition and the Xbox one Better Together Edition are not the same. The BTU is an inferior version of Xbox One Minecraft Edition based off of the Pocket Edition for
phone. It has extreme lag, chaotic menu system and broken redstone functions. I run Xbox One Edition not the BTU. So transferring to the new version of Minecraft for Xbox One has no relevance to me. They even state you need to transfer it to the Xbox One Edition
(the version I use) first which you can do. But once it is transferred to that edition it can not be used on that same edition.

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.

As Smwutches stated the Bedrock edition is the upgrade from Minecraft Xbox One edition, the only way to play the Xbox One edition now is if you
install it from a disc.

I believe that this upgrade of minecraft editions is to do with the whole minecraft cross play thing.
