What is the difference between 概念 and 观念？ I recently read on jukuu.com “  它使老的观念向新的观念转变。”   This sentence makes sense, but I'm trying to figure out whether it would be much different if I used a term like "概念“ instead of 观念. Is there a clear distinction between the two? 

Cheers
@Stan's comment is precise enough. To add my own interpret by deconstructing the words,

念 primarily means idea with a slight connotation of motivation/intention.

概 means brief; summary; abstract, hence 概念 is the abstract of the idea => concept.

观 is literally view, so 观念 is the idea as you see it => opinion; view.
