To transfer agents from Linux to Windows in the Pooled License:
1. Make sure that your license pool has been set up.
2. If your license pool has not been set up, you will need to contact your account manager and install the latest CDP Server (v. 2.14 or a later release).
In the client portal, click on the "License Pools" menu item.
Select the License Pool containing the agents you need transferred (if you have more than one).
You will be taken to an overview screen for your license pool. Based on availability, you will be able to transfer agents from Linux to Windows or from Windows to Linux by clicking the "Transfer" button.
You will now be taken to the input entry form to move your agents from/to the operating system of your choice. Enter the quantity of agents you need to transfer and click "Continue."
Once you have completed the input entry form, you will be taken back to the overview screen that shows the changed quantities.
