Fedora 33 network configuration (ifcfg*) migration guide available?

[Peter Boy]

With Fedora 33 network configuration is by default persisted in
/etc/NetworkManager/system-connections/*.nmconnection files. The old
/etc/sysconfig/network-scripts/ifcfg* files are „legacy“. They are still being processed
for the time being, but obviously it is time to migrate.
(cf https://fedoraproject.org/wiki/Changes/NetworkManager_keyfile_instead_of_...). 


Is there a kind of „mapping“ ifcfg-* —> *-nmconnection. ?


Most items are simple to migrate, but servers in particular sometimes have unusual
configurations, e.g. 

- for p2p Connections: SCOPE="peer xxx.yyy.zzz.aaa" 
- and corresponding a lot of (ADDRESSx / NETMASKx / GATEWAYx ) entries in route-{ifname}  
file

How do I handle that kind of config items in *.nmconnection ? The "search engine I
trust" couldn't answer that for me (or I couldn’t ask the right question).



Thanks
Peter
