The upgrade path to 5.08 from 4.0.12 If you have HA recommend that you upgrade the Passive first until you know that traffic passes and all features link VPN, IPsec in any works Export out your running-config.xml from the PAN so you have a backup in the event you need it. Download and do not install 4.1.0 Download and install 4.1.15 After the reboot and auto comm completes. From the Active device suspend so the passive takes over as the new active. Once you are sure all works then repeat on the active device. If you want to see what bugs and changes have gone into release 5.0.8 from the software link in the DEVICE TAB once you are running with 4.1.15 you should see the release notes. You can also log in to your support portal and under software you can download the release note from there. Hope this helps and if you like you're always welcome to call in for further assistance. Thank you
