Config adjustment

Hi all 

We have had our paradigm system for 11 years and it works well 

Had a few changes over the years I'm currently hopefully getting one of our suppliers to do some further config changes for us 

One thing I would like some advice on

Our dimmers in our Concert hall run on universe 1 

Paradigm controls various things through the dimmers 

Working whites and blues, house lighting including a show state glow,and recordable performance presets 

My question is Is it possible to change all this to universe 21 easily or will the programmer need to start from scratch?

I'm feeling if it's the latter it could be cost prohibitive
