How to export and migrate NetworkManager settings to new system?

How to export and migrate NetworkManager settings to new system? Use cases are: - reinstalling a machine - moving network configuration from laptop to desktop system (or vice-versa) All settings should be migrated, that includes: - default and custom network connections - wifi connections with passwords - VLAN configurations - VPN configurations (with keys if possible) I checked on Arch wiki and it there is nothing on migration, so I'm asking you guys and gals here.
