Hello everyone

I need some help with rotating an entire assembly:

As you can see, I've started the assembly with the white part in the middle, therefore all the planes are aligned to it. It was my intention to make the mold parallel to the part but due to some operacional limitations I had to model it in a different direction and the mold ended up rotated like this. All the parts are created in the assembly with relations to each other. So here is my question, is there a way to rotate the whole assembly to be parallel to the planes and don't brake any links ? I'll go ahead and say that I don't want to create a new assembly and insert this one.

Thanks
