yeah, a search would do you a lot of good here...personally I played about 50k hands before I moved up to 2/4. However, I jumped right from .5/1 to 2/4 (which i don't recommend). I probably could have moved up sooner, but I lacked the confidence.

I then played 50k hands of 2/4 before going into 3/6 6max with almost no previous 6max experience (another move I don't recommend).

But really, what it comes down to is BR and comfort level. If you think you might be ready, take a shot and move down if you lose. If the 2/4 game looks particularly good one day, sit for a session and see how it goes. There's no rule that says you have to exclusively play one limit.
