From shellyforhass to native integration

Hi, I have a question…if I would migrate from shellyforhass to native integration what I have to do?
I have to delete the configuration.yaml entry and after go to integration page and start a new config from zero?
After new configuration Shelly device name will change?
I have to change all script / automation reference?

None have made that step?

I have moved and all device names were changed. I had to change all configurations, automations etc.
