Is it possible to upgrade a Debian 8 (Jessie) to 9, 10, 11 and eventually 12? It is reccomended to upgrade one release at a time. But! 9's repositories are archived. How can I upgrade form 8 to 9?

Thank you in advance!

Yes that's the recommended path.

Information on how to upgrade can be found in the official documentation:

https://www.debian.org/releases/buster/amd64/release-notes/ch-upgrading.html

As others pointed out it might be a PITA. Depending on your installed software and configuration a new install might be easier.
