Finally I decided to upgrade my home server from Debian 11 Bullseye to Debian 12 Bookworm; here you can read some notes about the upgrade: Aggiornamento da Debian 11 Bullseye a 12 Bookworm.

One change that deserves a dedicated page is the upgrade from MapServer 7.6.2 shipped with Debian 11 to MapServer 8.0.1 shipped with Debian 12; in fact it happened that almost all MapServer based applications stopped working.
