I think it's ok too move up if you're confident about your game and are mentally prepared for the bigger swings (+/- 2K in a day is pretty normal). The higher variance is only a problem if you're a breakeven or marginal winner though, let's say long term 0-2 bb/100. 20 buyin swings are not uncommon then.
What do you think are your biggest problems when moving up then? Anything specific or is it just generally?
