I would like to upgrade Debian with BIRD. 10 to 11 and finally to 12.

I have several VM Debian  machines without BIRD   and this tutorial works for me. https://www.cyberciti.biz/faq/update-upgrade-debian-11-to-debian-12-bookworm/

Can I upgrade my servers Debian 10 with BIRD 1.6.6 to new Debian and BIRD 1.6.8 without problems ?
