Is your PC version on Java? Give me a bit more information on the issue and i'll do my best to assist you. ^TK

Yes It is. PC version is Java (and still is?) Xbox version is whatever normal version is available for Xbox x

That's the issue then. The Java Edition and Windows 10 edition of the game are not cross compatible so you're not able to transfer your Realm over. If you purchased the Windows 10 version on PC then you could sign into your Microsoft account and just access it from there. ^TK

What’s the windows 10 version called? How do I know the difference? If I purchase the windows 10 version can I then do the transfer?

The Windows 10 version is called Bedrock! Here's an FAQ with more information about the differences between Bedrock and Java: bit.ly/3dbD54p ^BT

Great! Will this allow me to move my world over?

As long as you have the same Microsoft account on both your Xbox console and your PC for Bedrock, then you should be able to transfer your world(s) between devices. The steps to do so can be found here: bit.ly/3ceMvvc. ^FF

Great! Last clarification. Can I put my Java world (the one I want to go to xbox) into bedrock?

Unfortunately, content cannot be transferred between Java and Bedrock Editions of Minecraft, which means you won't be able to upload your Java worlds to Xbox. ^AM

So…I did upload my world to bedrock using clunker. So now that it’s on bedrock, I can get it to Xbox correct?
