Defined in:

Overview

AMI is registered. Now only cleanup is missing, i.e. shut down instances and remote the volumes that were created. Start with cleaning the ressources in the local region. Steps:

- cleanup source region
  - unmount temp volume
  - detach source and temp volume
  - terminate instance
  - delete source and temp volume
- cleanup target region
  - unmount temp volume
  - detach temp volume
  - terminate instance
  - delete source and temp volume
