Scale assets AND Mecanim animation Keyframes?

I have been working on animations ~100s of keyframes in Mecanim in a scene, but because of a change in a plug-in, I have to upscale EVERYTHING 10x. If I do it in the import settings, the scale increases per vertex on the meshes and it all goes to hell - my animations are useless. Is there ANY way scale up my scene without having to re-keyframe everything?!

Ok - I’m so relieved this worked, but I parented everything into an empty game object and scaled the parent game object. Everything except for the particle emitters scaled perfectly without issues. Hopefully this will be useful for somebody else!
