Hi

Currently, I have around 100 machines running in ubuntu-20.04 each with a different networking modes (networking bond, single to multiple interfaces etc.). Networking on these machines is being managed from /etc/network/interface file and service networking. Now I am planning to migrate all these to Netplan.
Is there any tool that can help me to migrate network interface details (IP,GW,DNS, Bonding, etc) to yaml format for Netplan.

Thanks,

I don't know the answer, as I don't know what makes netplan or yaml attractive for static IP configuration. I just purged all related packages of both from another Jammy installation, with systemd-networkd taking over, as now on most of my installations regardless of distro.

I found a migration script on the system located under /usr/share/netplan/netplan/cli/commands/migrate.py (Also available under https://github.com/canonical/netplan...nds/migrate.py). This script, when executed, runs smoothly for the network interface (/etc/network/interfaces) with the non-bond interface, for interfaces with network bonding, it terminates with the following error.
