What is the saying?

A friend has heard a saying from somewhere but cannot recall what it is - about tearing down something old to make way for something bigger, stronger and better.

I know this sounds a bit vague. Can you think of any such saying in English?
Thanks.

The most common saying would be: "Out with the old and in with the new!".

I'm sure you are looking for a saying that is more specific; I'll keep thinking!
