It's done... Today we have finally moved away from socket-based licensing and are obtaining the new licences directly from a service provider.
At least it has already worked at a second location, while our main data centre here still needs an adjustment to the firewall. (The entry under "Backup Infrastructure" cannot check the SSL certificate.)
However, I noticed something there straight away, which I have already asked our service provider about via Teams - but perhaps you are a little quicker

The licence information shows me 22 recognised VMs in the Instances tab. However, there is also a multiplier of 11, resulting in 242 instances. Where does the multiplier come from or how does it come about? When I look at the whole thing via "Manage...", the number 11 instances appears after each individual VM.
