You can decommission a version through the Builder. To do this:
- Open the project
- Go to the Overview Tab
- Select the version that you want to decommission from the versions dropdown that is underneath the project name
- Click the menu (3 vertical dots) next to the New Version button. Then click ‘Decommission version #’
- If you want to decommission all versions, then click the ‘Archive all versions’
If this project version is already Deployed to Production, you will be prompted with a message. Click Yes to proceed. This will decommission the version in the Test and Production environments.
