Hi, There's a group of operators share there results and views on the migration from the Linuxbridge driver, check this thread for details: https://lists.openstack.org/archives/list/openstack-discuss@lists.openstack.... For dynamic-routing agent I suppose you reference the neutron-dynamic-routing project. n-d-r is tested with OVN backend in the last cycles (perhaps since 2023.1 Antelope release), so it should be fine for you to integrate it with OVN.

Hello openstack-discuss,
With the removal of the linuxbridge mechanism driver, has anyone successfully completed an in-place migrationfrom LinuxBridge to OVN? I did come across this https://www.jimmdenton.com/migrating-lxb-to-ovn/ and that looks good as a one-shoit while biting the bullet and taking a full outage. However, I was wondering if it was possible to run lxb and ovn side-by-side and cut them over, say one network at a time.
This particular deployment was stood up using openstack-ansible back in the rocky days (now running antelope) and it appears that openstack ansible's default was lxb up until Zed.
Any suggestions or recommendations on the best path forward?
Also, will the dynamic routing agent work with ovn?
