It depends how you use it. You can ask Claude Code for instructions to migrate the Code yourself, and it will be a teacher. Or you can ask it to create a migration plan and the execute it, in which case learning will of course be very limited. I recommend to do the conversion in smaller steps if possible. We tried to migrate a project just for fun in one single step and Claude Code failed miserably (itself thought it had done a terrific job), but doing it in smaller chunks worked out quite well.
