AppStudio 9 adds support for Bootstrap 5. Bootstrap 4 continues to be supported by the Bootstrap team, so there is no need to convert. Bootstrap 5 brings a number of improvements and refinements.

There are many changes in Bootstrap 5: more than we could build a migration for. Bootstrap 5 is a separate framework. We will continue to support Bootstrap 3 and 4 for existing projects, but recommend using Bootstrap 5 for new projects.

We were able to accomodate most of the changes within our code, so most of the controls work pretty much the same way as they did in Bootstrap 4. The code emitted by AppStudio is quite different.

Since Bootstrap 3, 4 and 5 share many internal variable names, controls from the two frameworks cannot be included in the same project.

Here's are a couple of detailed summaries of the changes from Bootstrap 4 to Bootstrap 5:
