[magnum][kolla ansible]Ask about use higher magnum image on previous opentack version

Hello guys. I use Openstack Xena by using Kolla Ansible tool. due to some reason, I want to use Zed Magnum on my current system(Xena). Can I do this task by rebuilding Magnum images from code then retagging and replacing the Magnum container with new images? Any experience for this? Thank you very much. Nguyen Huu Khoi
