New V3 Hub - Start over or try to "migrate"?

Migration from V2 to V3 Hub

Hello! Having some trouble with my v2 hub, so decided to upgrade to the v3 hub (as yesterday Smartthings support said there would be an option to migrate in the app once both hubs were installed). Low and behold, ordered the v3 and installed today, no migration option exists in the app. Called smartthings support again and they said the option was removed and that I should post out here in the dev community to get assistance migrating from v2 to v3. Anyone know if it’s possibly without setting everything up from scratch? Thanks much! Travis

How do you reset SmartThings, remove all devices and apps, and start over?
