The original and target instances should have the same Android version. If versions are different, we cannot guarantee the result.

  1. Stop the original instance with the attached Block Volume.
  2. In the Resources > Attached Block Volumes section, click on the 3 vertical dotes at the end of line of the attached Block Volume and select Detach:

  3. The Block Volume will now be available for other instance.

  4. Start your target instance and attach the volume to it - see steps 8-12 from previous chapter.
  5. The target instance will automatically reboot.

The original instance internal storage /data will then replace the target instance one - all the applications and settings installed in the original instance will be available in the target instance.
