Previously, a router that was neither an HA nor a DVR router could not be converted into an HA router. Instead, it was necessary to create a new router and reconnect all the resources (interfaces, networks etc.) from the old router to the new one. This update adds the ability to convert a legacy router into an HA or non-HA router in a few simple commands:
# neutron router-update ROUTER --admin-state-up=False
# neutron router-update ROUTER --ha=True/False
# neutron router-upgrade ROUTER --admin-state-up=True
Replace ROUTER with the ID or name of the router to convert.
