Hey junior

Thank you for taking the time to post this on the Xbox Forums. We understand that you are inquiring about transferring DLC from the "Minecraft Xbox One Edition" to "Minecraft"

In regards to this matter, as per the
Minecraft Better Together FAQ:

"Most content items will transfer over, be available to be used or purchased on any Bedrock Engine platform and be used in multiplayer with a few exceptions due to licensing restrictions:

However, when I got "Minecraft" I had to purchase all my DLC once more. My recommendation would be to either wait for you to convert to "Minecraft" or head over to the
Minecraft Community and ask there to find much more accurate information.

I hope this was of some help.

Some Minecraft skins cannot be transferred from Xbox 360 to the Xbox One. The Doctor Who Skin pack might be one of those packs.

I checked online, it turns out skin packs released before September 5, 2014
can be transferred over. Any packs released after that date cannot, and you would have to purchase those packs again on the Xbox One.
