The 3scale documentation includes in each release a supported configurations article which provides the versions of the different components that are compatible with the 3scale version.
When planning an upgrade customers should study the supported configuration document for each version and check the supported path. This is some times difficult since involves checking OCP version, RH-SSO version and database versions.

The request is to include in our documentation a visual aid that helps visualize the compatibility of the 3scale release with OCP and the other related products at a glance as well as an example of supported migration path, as published in this KCS solution or something similar.
