I work for an enterprise. We automated the change control process and integrated it with our CD dashboard. So a quick peak at the dashboard will tell us.
Though depending on the criticality of the app. We may only retain a previous release for a specific time period.
It's just doing another deployment. It doesn't matter what version you are deploying.
That's the whole point.
My teams go into their CI/CD platform and just cherry pick which build they want to release.
