How do I backup and restore network and drive configuration?

I am planning on upgrading to a larger NVMe, and re-install Proxmox this week. I have my VM's backed up, but the time consuming part of a reinstall is seting up the data drive(s) and network bridge(s) setup. Is there a way to backup those settings, and restore them on a new install?

For network, copy in the interfaces file.

Backup /etc/network/interfaces, reconfigure it, and then restore it.
If there are SDN settings, also back up /etc/network/interfaces.d/sdn.
