Tvheadend

Dear all,

im trying to move my tvheadend config to a fresh install of ubuntu 19.04. I copied all folder and i have same channels, muxes, bouquets and records but i realized that services are not in the tvheadend folder. Therefore channels are not associated to services. I have 200 channels to associate to services, are some way to associate it automaticly? Are there any folder in system where could i found the services in order to copy it from my old server to new one?

What is the better way to associate my channels with services?
