Rocky Release using Ubuntu 18.04 with netplan

I am currently using Newton with ubuntu 16.04 and would like to migrate to Rocky over Ubuntu 18.04. But I discovered that Ubuntu 18.04 is using netplan instead of ifupdown to manage the network ressources. I realize that it is more a Ubuntu question but since Openstack required quite a bit of complexity in the networking I think posting the question here is more adequate.

I have the following interfaces file for ubuntu 16.04 and looking on documentation on how to convert that setup to netplan ?

Any body can help ? Thanks

Here is my current /etc/network/interfaces file

This file describes the network interfaces available on your system

and how to activate them. For more information, see interfaces(5).

source /etc/network/interfaces.d/*.cfg

I don’t have an answer, but it seems you can still go back to the old way https://askubuntu.com/questions/10317.... Or here: https://netplan.io/faq#how-to-go-back....

There seems to be a migration tool, too: netplan ifupdown-migrate.

Thanks for your answer. Reverting back even if this is not my first choice, this is what I end up doing since I do not receive any answer from either ubuntu, openstack or netplan support.
