Beginning at ArcGIS 10.3, ArcGIS Pro connecting to Portal for ArcGIS requires an ArcGIS License Manager configuration. The same ArcGIS License Manager that manages concurrent use ArcGIS for Desktop, ArcGIS for Engine, and Esri CityEngine licenses will also manage ArcGIS Pro named user licenses via Portal for ArcGIS.
All previous functionality and configuration for ArcGIS for Desktop, ArcGIS for Engine, and Esri CityEngine concurrent use remains unchanged with ArcGIS License Manager 10.3 and newer.
For details on installing ArcGIS License Manager, please refer to the License Manager Installation and Startup topic.
Instructions for creating an ArcGIS Pro named user license file, authorizing named user license files on the License Manager, or exporting a portal configuration file from License Manager can be found in the Configure License Manager for use with Portal for ArcGIS topic.
Useful information and best practices for configuring the ArcGIS License Manager for use with Portal for ArcGIS can be found within the Useful Information and Best Practices topic.
Details for administering ArcGIS Pro named user entitlements in the Portal for ArcGIS can be found in the Portal for ArcGIS help documentation.
Information for managing portals and licenses with your ArcGIS Pro software can be found in the ArcGIS Pro Help.
