Sometimes I see a pop-up, that I can migrate to a newer kotlin version or something but I recently accidentally closed it and after restarting Android Studio it doesn't appear again. How can I run that migrations manually? Because, when I download a random project from GitHub I sometimes get compilation errors if something is not updated.

I was able to make the pop-up appear again, try the following:
- Change
kotlin_versionon your build.gradle to whatever version of Kotlin you were before or want to migrate from. - Sync Project with Gradle files.
- Upgrade again to the version you want to migrate to.
You can create a custom inspection profile to check if your code requires Kotlin migration. Go to bottom toolbar - Problems - Project Errors - Inspect Code (alternatively, Code - Inspect code... in the app bar), press 3 dots next to existing inspection profile, duplicate that existing profile, select only Kotlin - Migration for this new profile and run an inspection for it.
