When Change Sets Become Unavailable

A change set deployed from a source sandbox that you recently deleted or refreshed can temporarily appear available for deployment in the target org.

A change set is unavailable for deployment after the following events.

• The change set expires.
• The change set is deleted from the source org.
• After the change set is deployed from a source sandbox to a target org, the source sandbox is deleted or refreshed.

A delay can occur between when the source sandbox is deleted or refreshed and when the target org shows the change set as unavailable. The length of the delay depends on how long it takes internal database cleanup processes to complete. When the source sandbox is deleted or refreshed, assume that the change set is no longer available for deployment in the target org.
