URL Redirect is not available as an OOTB feature in APIcast / SaaS Portal. The purpose of this issue is to track the progress of this specific feature and to increase the priority/urgency due to the issue this creates for all current customers.
The issue is that if a SaaS customer wants this feature, a PR request needs to be made to upgrade their corporate account, and then they must update the APIcast source with the difference between their APIcast version and the redirect-url branch as referenced here: (https://github.com/3scale/apicast/compare/v3.0.0...redirect-url).
For an on prem customer, steps to upgrade the admin portal need to be documented.
For future releases, it is not clear if the 3Scale apicast redirect-url branch will step up to the latest release and provide clear direction to customers stepping up?
