Looking to transfer to another bank...help?

So I'm wanting to close my current bank account (it's a checking account) with one branch and open up an account with it's competitor - I'm just wondering about the process of closing an account. Is there such a thing as minimum closing balance or anything - like an amount of money you have to have in order to close the account? And is there anything I should be wary of / any possible harm or record I'll take for closing my account? Or is it as simple as going in, getting my money, them canceling my account, and me walking back outside, no strings attached? Thanks for the help in advance
