For in-game issues you should contact the game's dev (Mojang in this case) support or post in their support forums.

You can use the Minecraft Realms standard or try the steps below first when transferring worlds.

In Minecraft (Bedrock Version), select the Sync Old Worlds button at the bottom of the worlds list in the Play menu. This finds any worlds on the device from the Minecraft: PS4 Edition and displays them below the button.

Select any of the worlds that are displayed to convert it to the Bedrock edition.

After conversion, the world will show up above the Sync Old Worlds button, along with the rest of your Bedrock worlds.

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 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
