## Request new license files and serial numbers

If you're upgrading from WorkflowGen version 5, you must request a new license (trial, unlimited, or per user) and a new serial number for each of your WorkflowGen servers.

* The new license file must be copied to the `\wfgen\bin` folder.
* Define the new serial number in the `\wfgen\web.config` file (e.g. `<add key="ApplicationSerialNumber" value="WFG-ENT-XXXXX-XXXXX-XXXX-XXXX" />`).
