How to migrate from a game version to the next one on Android

First, you need to download a file manager. You can find “File Manager Plus” on the Play Store for free.

Grant access to the app to access all local files.

Go to Main Storage (or SD if the game is on a SD card) > Android > Data

It will open up a prompt, accept the prompt, and grant access to the Data folder by pressing the “Use this folder” button.

Go to com.random.extralife > files, and long press the saves folder. Copy it.

Go to any location on the phone, like Documents, Downloads or such, and paste the folder there. Your saves are now backed up.

Uninstall the previous version

Install the new version

Start the new version up, then exit it

Copy the saves folder from the backed up location

Paste it in Android > Data > com.random.extralife > files

Merge and replace everything

Start up the game, and enjoy your saves :)
