Following the draft for migration guide from template based OCP3.x installation to OCP4.x operator based deployment outlined in THREESCALE-2929 THREESCALE-2935 at the end of the process there are no routes in openshift to APIs using 3scale managed/hosted apicast that should be handled by zync.

This can be related to THREESCALE-4456 , anyway 2.5->2.6 upgrade guide [1] contained instructions to (re)create routes. Will be this necessary here?
