Immediately after the successful :command:`software deploy activate`

- Immediately after the successful :command:`software deploy activate`, before
attempting the Kubernetes upgrade.
- After attempting a Kubernetes upgrade which failed and was rolled back.

A rollback of a host major release software deployment can only be done
if Kubernetes has been successfully rolled back to its original

If a host software deployment needs to be cancelled before the software is
deployed to any host, that is, if the deploy state is either

deployment directly using :command:`software deploy delete`.
