…om minigraph parser (sonic-net#2890) MSFT ADO: 24419953 This is to fix a bug where warm upgrade from old image (eg. 20181130) to new image (eg. 202012) does not update docker_routing_config_mode to the new config expected the target OS. For eg., in 201811 DEVICE_METADATA.localhost.docker_routing_config_mode is set to unified. After upgrade to 202012 the value is not changed. However, the expectation in newer images is that the value is separated. The move from unified to separated was done as part of an old change: sonic-net/sonic-buildimage#2961 However, migration logic was not updated since then. Because of this miss, cross-branch warm-upgrade from 201811 to 2020212 to 202305 to latest will always keep the setting as unified. How I did it Added a common migration logic: update docker_routing_config_mode to the value from minigraph parser. How to verify it Added a new unit test. Updated old unit tests.
