If you need to scale it up quite a bit, it might start getting a little fuzzy, so you want to redraw it, but you can use your existing line as a guide (e.g. turn it into a stencil or use the Selection tool). It doesn't sound like you need to do anything complicated, but if you do need something more than a quick transform, describe what you're after and we can give you more advice ^_^
