Years ago (2020) I implemented a pretty basic freeradius installation (authentication only) in a school for WLAN access. That time I installed version 3.0.19 on a virtual server (Ubuntu 19.04) and used Samba to connect to Active Directory on Windows Server. This is still working fine but I think it is time for a larger upgrade of all involved components.

Yes, that's a bit old now.

Is there any recommendation/cookbook/guideline how to do that upgrade in the most efficient way with minimal effort?

It's a virtual machine, so you're pretty safe... - Snapshot or clone the VM - Upgrade everything - If it doesn't work, investigate or roll back There really shouldn't be anything to be concerned about upgrading from 19.04 to 24.04 and from FR 3.0.19 to 3.2.8.

Of course I can do everything from scratch on a second virtual machine. Is that the preferred way? Or can I copy the freeradius configuration over? Any changes I have to do then? Config from 3.0.19 should be fine on 3.2.8.

Yes.

No. You can upgrade a system in place, and the FreeRADIUS packages will *never* over-write an existing installation. Or, just copy all of the configuration files from the old system to the new one. Just double check that all of the paths at the top of radiusd.conf are the same. If not, edit them so that they're correct for the new system. Everything else depends on either relative directories, or those paths. And with the exception of a few things that no one used, the configurations are 100% compatible between 3.0 and 3.2. Alan DeKok.
