Upgrade from CEntos 8 Stream to Red Hat 8 with developer "subscription"

Good morning all,

self-taught, like many people in linux, I am working on HP servers (DL 380 G7, DL 380 G8 and p4500) for personal use and to naturally evolve under linux. I have used Debian for years. To get closer to a more "professional" system and to be able to use HP software more easily on my servers, I recently decided to switch to Centos 8. Recently the announcement has come that this version will be abandoned and that we will have to switch to Centos Stream, which I did via the automatic migration.

Now, since February 1, it is possible to use Red Hat Developers in production.

So my question is; is there a script, a code, ... to switch from Centos 8 Stream to Red Hat 8 automatically like the one used to switch from centos 8 to centos 8 stream.

There is indeed convert2rhel, unfortunately it does not work with centos 8 stream ...

I would like to avoid having to reinstall and reconfigure everything.

Thank you in advance for your answers.
