Hi,
- For one RDS deployment, you can use only one Licensing mode (Per User or Per Device). That means you cannot use both device-based and user-based cal at the same time.
- Both the licenses (device-based as well as user-based cal) can be installed on the same server, because you can use the same licensing server to issue CALs for different RDS deployments. For example, you have two RDS deployments, one licensing mode is per user and the other is per device. You can specify the same licensing server for them, and it will issue the two types of CALs respectively for these two deployments.
