@RobertKircher - I recently saw this in the Developer release notes for UNv7 support in the Maps SDK
Release notes for 200.5 | ArcGIS Maps SDK for .NET | Esri Developer
Question regarding those sites that are part way through implementations on 11.3 using a v6 UN because of the previous advice not to go to v7 until BIGINT ObjectID's are supported in the Maps SDK. At which point in the Network Release cycle of Enterprise should we start thinking about moving off of version 6? This will have a bearing on future upgrades etc.
