Description of the bug

https://github.com/sonic-net/sonic-utilities/blob/master/scripts/db_migrator.py#L138
try:
if os.path.isfile(MINIGRAPH_FILE):
minigraph_data = parse_xml(MINIGRAPH_FILE)
except Exception as e:
log.log_error('Caught exception while trying to parse minigraph: ' + str(e))
pass
If there's SonicQosProfile in minigraph, parse_xml fails, because select_mmu_profiles needs platform.
https://github.com/sonic-net/sonic-buildimage/blob/master/src/sonic-config-engine/minigraph.py#L1925

Steps to Reproduce

Add SonicQosProfile, warm upgrade from 202305 to 202405:
<a:DeviceProperty>
<a:Name>SonicQosProfile</a:Name>
<a:Reference i:nil="true"/>
<a:Value>Balanced</a:Value>
</a:DeviceProperty>
