A Concurrent Use license enables multiple users to share access to ArcGIS Pro from any computer on a network or from a virtual machine. ArcGIS License Manager software installed on the network manages the distribution of a pool of shared licenses.
The number of Concurrent Use licenses in the shared pool determines the number of users who can use an application at a given time. When a user starts ArcGIS Pro, the application sends a request to ArcGIS License Manager to determine if a license is available. If a license is available, the application starts, and the number of available ArcGIS Pro licenses decreases by one. When the user exits ArcGIS Pro, the license returns to the pool.
Because ArcGIS Pro uses the Named User license type by default, a license conversion is required before Concurrent Use licenses can be authorized.
