Company Director entering third-party employment

Hi.
I am a director of a limited company, and have been paying myself a small salary.
I am planning to become an employee of a different organization (while still maintaining my position as a company director).
I plan to stop paying myself that salary, and only get the salary from my new employment.
I would like not to pay a higher tax on the new job.
How should I act in this situation?
Thank you in advance.
