Proper upgrade from portal version 7.4.x
According to former documentation, it was mentioned to deinstall the portal if it's a version earlier than 8.0.x before doing an upgrade. The actual document from 31rd of October that indicates "Install: Cireson Portal - Installation and Upgrade Instructions - This article applies to: Cireson Portal, version 7.0.X and above." doesn't mention anything about deinstalling the portal prior to upgrade to the new version.
What's the proper upgrade path of the portal now? We're still on 7.4.x, I wasn't allowed to upgrade for different reasons. SCSM is version 2012 UR9. Thanks for your feedback.
