Will the firmware from the old HDD work on PS4? Swap the old and new hard drive.

In this video, I will do an experiment. As a result of speed tests of games from past videos, I still have an old factory hard drive with an operating system installed. And in this video, I will return the old HDD to PS4 and see if the system will accept it. Will the old firmware work? Let me remind you that rolling back the firmware using this method is impossible.
