Now most of you know it's not automatic, you have to select the planet, click the little ore truck on the button bar, and use the dialog to select from what resource to what resource, etc.

But remember, you can only convert from you have in storage into what you can store. Ran into that little problem in my neutral challange game. I only had two systems, every planet was maxed out value with monoliths ... but I couldn't convert into all the minerals I needed -- I didn't surrender enough space on resource storage.

Long story short, look at the empire screen critically and see where everything is going, and what you have, and try to predict what ships you still need to build. Turn your excess organincs and rads into (minerals-30%0). Is that enough minerals? And do you have mineral resource storage to hold that?
