The only downside I can see to using a ceramic capacitor in place of an electrolytic is if temperature stability is an issue. A 10 μF capacitor in ceramic is going to be made with a high-K dielectric having a Y5V or Z5U temperature characteristic, and these have very large temperature coefficients. In a circuit where temperature stability of capacitance is important, they might not be a good choice.I know ceramic is better for high frecuencys, but if I have a circuit with a 10uF electrolytic capacitor and I change it for a ceramic one, ¿what could be the problem?
Excellent article, OBW0549!The only downside I can see to using a ceramic capacitor in place of an electrolytic is if temperature stability is an issue.

This technical article at Digi-Key gives the details...
