We had deployed StarlingX 4.0 in Bare metal Standard with Controller Storage Mode. We have also installed Openstack application from StarlingX cengn mirror stx-openstack-1.0-49-centos-stable-versioned. On the top of Openstack, few workloads are also running.
There is an option to upgrade starlingx software release from 4.0 to 5.0 without hampering the existing configuration and in a seperate link, openstack patch upgrade is also possible
