DMX adress shift to another dmx universe

Hello, I am in a preproduction for a show. Theater technicians communicated me that I will need to shift some of my DMX adress into another universe, but didn't communicate exactly to which one. 
I suppose this change will be made during final setup. 

Question is: 
Will it affect my existing cues regarding this lights that were programed into Universe 1 (exmpl DMX 100) if i make a patch change on a flight in loction (exmpl of a change DMX 2/100)???? 

Please let me know it would be a huge help
