VirtServer - Licensing in Private Networks
About on-premises licenses
From VirtServer 3.16 Release and onwards, ID-based licenses are controlled by the License Servers hosted on your premises. Once configured correctly, VirtServer connects to this server to check if a license is available or not. Once a license is available, it will be requested, assigned, and installed.
The license type name – on-premises – indicates that the license is controlled by a server running on your private network. This is contrary to the license type – online, which means the license is controlled by the SmartBear license server available online.
Notes
An on-premises license is bound to the On-Premises License Server (Currently the default SmartBear ID-based license option for VirtServer, available from Version 3.16).
To move and use the license on another computer, you need to uninstall it from the current one. For details, see Uninstalling On-Premises Licenses.
