undercloud.conf for OSP10->OSP11 upgrade
https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/11/html/upgrading_red_hat_openstack_platform/chap-director-major-upgrade#undercloud_upgrade
One more variable should be set to keep the old 192.0.2 ranges for an in-place installation: "inspection_iprange"
If you don't, here's the output that you get:

As soon as I set that variable to use the old range, 192.0.2.100,192.0.2.120, all good and no problems.
