https://github.com/Azure/maximo#step-2-deploy-and-prepare-openshift indicates that the current version of OCP in ARO is not supported, however ARO is currently running OCP 4.11
The official IBM software compatibility reports indicate that MAS 8.10 runs on OCP 4.10 and later.
Is the doc in this repo out of date, or is there another constraint that prevents deployment of Maximo on ARO?
