It depends. I think web-workers are handled differently, so if one of your dependency uses the webpack way to import a web worker then you might have to ditch that library. There might be other painpoints, but I think most projects migrate pretty easily. I recently migrated a vue2/vue-cli project over to vue3/vite. I had a pretty clear migration path, and did it incrementally over a few months. I needed to ditch a few libraries that didn’t work with either vue3 or vite. Most of the replacements work with both (e.g. vue-composition-api or pinia) so I could keep using vue2 while I migrated and then when the last non-compatible code had been refactored a few months later the final migration was fairly straight forward. The vue-cli switch happened somewhere in the middle of this.
