I can convert older worlds with large file sizes no problem but any of my most recent worlds from Minecraft Xbox One edition in smaller size crash at 9% I know this is an issue because I've heard other had this same exact experience. I'm pretty bummed that I can't play on my old words because they will not convert.

If you participate in the beta. Can you upload your world to the developers and mention the receipt number in this report or take a screenshot of the receipt and add it to the ticket?
Beta only. Highlight the pre-conversion world you have issues with. Press Y. Follow the dialog and upload the world. Once the upload has finished you will see a receipt. Supply the receipt on this ticket as a image/screenshot/photo (clearly readable) or text. So a developer can search for your world.

It seems to only crash on worlds I've made from 360 and converted over to the Xbox One version and then to the BTU edition. Worlds made on Minecraft Xbox One edition seem to convert smoothly.
Thank you for your report!
