Direct answer
The short answer
Existing wiring can sometimes be reused, but it must be inspected and tested before that decision is made. Cable type, condition, routing and the requirements of the selected equipment all matter. WeTech takes a retrofit-first approach and reuses suitable infrastructure where practical rather than promising that every old cable will work.
