Dear Mojang support,
I've played the same map with my kids since 2010 and we just recently wanted to migrate to Xbox One version of the game to keep playing with the newer updates, as the X360 is no longer supported, but it seems I can't get the map to appear after uploading it to the cloud through the in-game save uploader, and after using syncing the old worlds in Minecraft for Xbox One. The game itself (on X360) can differentiate if the map uses the Update Aquatic or not (syncing old worlds without TU72 says it will be compatible on Xbox One Edition but our map, with TU72 says this map will only work on Minecraft 2017 version) so there should be a dedicated support for that I presume.
I'm confused, so can I transfer the map or not? I've dealt with the official Xbox support and they adressed me here.
Thank you for your reply,
