I updated HA to the latest firmware (2022.2.2). I know a few of my integrations are now officially supported. Is there a way to migrate the HACS version over to the new native integration? Do you have to delete the current version and just start new?
You will probably need to remove the integration from Configuration->Integrations, remove it from HACS, and add the integration back to Configuration->Integrations.
If you want to give a try without setting up all the stuff from stratch, shut down home assistant, remove the custom_components/integration_name folder and restart home assistant. Let’s hope they will work fine assuming that custom integration and new core version are sharing the same domain name. If this doesn’t work, follow the advice above
