   > After some research, I found the behavior of serial execution was changed at #9869.
   > 
   > In the first version #6185, serial execution works on all process instances.
   > 
   > After the #9869, SERIAL_WAIT/SERIAL_DISCARD/SERIAL_PRIORITY only works on the same version process instances.
   > 
   > To fix this issue, I have 2 ideas:
   > 
   > 1. Recover the serial execution logic back to [[Feature-#6268][server-master] Serial execte process #6185](https://github.com/apache/dolphinscheduler/pull/6185). But also need to fix [[Bug-BE] Task flow definition cannot execute serial task flow while parallel serial alternate running. #9868](https://github.com/apache/dolphinscheduler/issues/9868), such as applying the [commit](https://github.com/apache/dolphinscheduler/pull/9869/commits/8b6363d2d38b961105202e0c4b405fc511f2ad56)
   > 2. Based on 1, add `VERSIONING_SERIAL_WAIT/VERSIONING_SERIAL_DISCARD/VERSIONING_SERIAL_PRIORITY`.
   > 
   > I prefer the first one.
   > 
   > Can you give me any advice?

   I don't think we should support cross version execute strategy, it will make users misunderstand earsily.
