how to scale a scene down

I have built my project too big, and I need to scale it down to 10% of its current size. The scene has VDBs in it so I would want the clouds to keep their internal scale. And also all the lighting needs to move and adjust in a relative way.
I thought I could just put everything in a combiner and scale the combiner down, or parent the combiner to a locator and scale that down. This doesn't seem to work, the lighting looks different and so do the clouds, or maybe its just the lighting.
Any suggestions on how to scale a scene down? Or maybe I am approaching it the right way but there are some things that just down scale?
