With the release of Debian 11 "Bullseye" comes the obligatory advice to upgrade your server systems to the latest version or to check the feasibility of doing so.

We strongly recommend our customers to keep the 2-year cycle and to perform these upgrades on a regular basis or have them performed by us.
