How to archive and unarchive releases in CDD ?
Release : 7.1
Component : CONTINUOUS DELIVERY DIRECTOR
An archived release can be duplicated in case you need to create new release based on the same configuration.
There is no option to "unarchive" a release.
When you archive a release, it actually means the release has completed - the same application/applicationVersion is (usually) not to be re-released and a new applicationVersion would be used.
So, if you duplicate the release, you change the releaseVersion and you will be able to configure the applicationVersion as needed.
