Change the Role for an Instance of Revit Server

Each instance of Revit Server is assigned up to 3 different roles (Host, Accelerator, or Admin) at the time of installation. You can modify the RSROLE2025 Release environment variable to enable or disable roles as needed.

Important: If you are switching the Host role from one instance of Revit Server to another, you must perform additional steps before and after editing the environment variable. See Switching the Host Role from One Revit Server to Another.
