If you're looking for how to transfer your Minecraft worlds between devices, please go to Transfer Minecraft Worlds to Another Device.
We're often asked if players can download Minecraft for free after purchasing it on a different device. Unfortunately, this is not possible. This is because Minecraft is sold and licensed separately on each platform, and transferring licenses is not possible as each platform has their own marketplace.
An example: You bought Minecraft on a Nintendo Switch and want to transfer to an Xbox One. You would need to purchase a new copy on the Xbox One.
Deleted Minecraft applications can be re-downloaded using the same store account and device type on which it was purchased. You can visit your device's marketplace, search for Minecraft, and re-download the app for free.
For more information on these policies, please consult your platform’s marketplace support center.
