Moving from L.6 to L.7 and Bootstrap to Tailwind

I have an application that was developed in Laravel 6 that we are upgrading and moving it to Laravel 7. Among the things that we want to do is to also move from Bootstrap to Tailwind, because we want to have different look. I found a converter for Tailwind called TailWindo that seem to do a pretty good job converting the Bootstrap classes. When the app was created we used the php artisan ui bootstrap --auth, then we run npm run dev to push it in to the app.css file. My questions are:

• Is there a command to un-scaffold the application?
• I see the steps to upgrade in the Laravel web site. Do you have any suggestions for this to go smoothly? We did a test run on a copy of the application and it was rough, we dump the test after several tries.

Thanks
