Hi,
If you are in need to remove OpenVPN Access Server ( OpenVPN-AS ) license from one server so that you can re-issue a new license from OpenVPN and move the license to new server, do the following to revert back OpenVPN Access Server to it's default license (2 concurrent connections),
---------------------------------------------------------------
1. Login to the server via SSH.
2. Remove the license file which is located under /usr/local/openvpn_as/etc/licenses .
#cd /usr/local/openvpn_as/etc/licenses
#rm -f XXXX-XXXX-XXXX-XXXX.lic
3. Restart OpenVPN Access Server.
#service openvpnas stop
#service openvpnas start
4. Login to Admin GUI and confirm that the license is now removed
