The Projects tab shows a chronological listing of all deployed projects. Those deployed most recently appear at the top of the list.
You can revert the target site to a particular deployment state by selecting a project from the list and clicking Rollback to Selected. This behavior starts a deployment that rolls back all projects deployed after the one you selected.
When a target site is rolled back to an earlier project, those projects whose assets are no longer on the site are shown in grey.
Roll back Constraints
Two constraints apply to roll back deployment:
You cannot roll back deployment on a target site while an active deployment is in progress on that site. If the roll back operation is urgent, you must first revert all active deployments. In general, a roll back deployment can succeed only if the target is unchanged in the interval between when you schedule the roll back and when it actually executes.
You cannot roll back deployment on a one-off target; the Projects tab for a one-off target site is read-only. If you perform a full deployment to a one-off target, the Projects list is emptied when deployment is complete.
