How to change your career path to be a functional tester

I have been about 7 + years into Performance Testing as well as a DevOps engineer.Before coming int Performance Testing, I did some manual testing and extensive development in .Net and C# .However due to family issues I would like to work near my home and the only jobs available are in functional testing.Can you please suggest some skills I must have on my CV to get a job in functional testing?
