Fuel 8.0 changed default external network type (local → flat).

This is causing connectivity issues(no external connectivity) while upgrading MOS from older versions.

# Workaround (Tested for 6.1 -> 8.0)

Execute after "octane upgrade-control"
(new controller)
service neutron-server stop
crm resource stop clone_p_neutron-plugin-openvswitch-agent

mysql -e "insert into ml2_flat_allocations values ('physnet1');"
mysql -e "update ml2_network_segments set network_type='flat' and physical_network='physnet1' where id in (select network_id from externalnetworks);"

service neutron-server start
crm resource start clone_p_neutron-plugin-openvswitch-agent
