Unless you want a very rough paint look, you would need to scrape off the old paint, then sand down the surface to get a good, smooth result from painting.

Can I paint semi gloss over flat paint? Thanks!Barbara Phillips
Yes, you can.
yes
Yes, you can.
Yes. You can paint semi-gloss latex paint over flat latex paint. It is not advised to paint over any latex with any oil-based paint. Nor is it advised to try and paint over semi-gloss paint with any other finish without first de-glossing the finish and priming.
Yes. You. Can
A quick easy way is to apply a crackle overcoat, like the ones made by OPI and Sally Hansen, to nail polish. You can also have a custom crackled look done for you in a nail salon.
