How can I migrate the android version of my odk collect? What files should I affect to generate the new apk?

Hello @Jennifer_farfan_luna, welcome to the ODK Forum when you get a chance, please introduce yourself on this thread.

Do you want to upgrade to a newer version of ODK Collect, or are you trying to migrate your current setup to a different device?

Are you migrating your existing collected data and forms, or are you looking to transfer the app itself?
