Difference between 10 nl (6max) and 25nl (6 max)??

[mg0698]

I didn't know where to post this but was wondering if any one can give me some tips, or advice? I have been playing 10 nl (6 max)at pokerstars for a little bit i have almost 20,000 hands and have been doing well. Just wondering when is the right time to move up and is there any major differences between 10Nl (6max) and 25NL(6max). Any suggestion is appreciated thank you.
