I am doing a clean install of a sick system (very slow, connectivity issues), for which I never identified the problem.
My original system was built almost completely in yaml, before the UI came along.
Should I rebuild in UI or copy blocks in yaml. For example, timers, and simple automations. I have a few automations that might not work in UI - not sure.
You need to move to UI only integrations which were moved to UI - like ping.
Moving template entities - not needed.
Moving helpers - not needed.
Moving dashboards - not needed.
Moving automations to UI - not needed. Just give them unique “id” (if you have not) to see traces etc.
