If you want to move from the trial Novell BorderManager 3.8 product to the production version, you do not need to re-install Novell BorderManager 3.8. Follow these steps instead:
Install the Production License from the licenses\regular directory on the product CD, using NWAdmn or iManager.
Uninstall the trial VPN client. Install the production version of the VPN client from the product CD (cl_inst\vpn\exes\setupex.exe).
Uninstall the trial NCF. Install the production version of the NCF from the product CD (cl_inst\ncf\ncfInstall.exe)
