Rule to remove projects once moved to archive project

I am trying to find a way to remove all projects, once I move that tasking to a different project under the same team. The taskings is started by the management but then moved to employees but with an additional project added for that set of employees. Once completed the managers must manual remove the second project from the tasking. This takes time since the tasking my be assigned to multiple projects before being complete. Once verified compete the tasking is moved to completed tasking project that is held for one year (To reference back if needed). I am looking for a way to remove all projects once I move that tasking to the completed project. Any help is welcomed.
