You may think of 1.0.0 as VC7.0. + +Vyatta release compatiblity +--------------------------- +Vyatta Core releases from **6.5** to **6.6** should be 100% compatible. + +Vyatta Core **6.4** and earlier may have incompatibilities. In **6.5** the "modify" firewall was removed and replaced with "set policy route" command family, and old config cannot be automatically converted. You will have to adapt it to post-6.5 syntax manually. + +.. NOTE:: + Also, in **6.5** remote access VPN interfaces were renamed from pppX to l2tpX and pptpX, so if you are using zone-policy in pre-6.5 versions, make sure to change interface names in rules for remote access VPN. + +Upgrade procedure +----------------- +You just use "add system image", as if it was a new VC release. The only thing is that is you want to verify image digital signature, you will have to add the public key. + +.. code-block:: sh + + vyatta@vyatta:~$ '''wget http://vyos.net/so3group_maintainers.key''' + Connecting to vyos.net (85.159.113.32:80) + so3group_maintainers 100% |*************************************************************************** + ********************************************************************| 3125 --:--:-- ETA + vyatta@vyatta:~$ '''sudo apt-key add so3group_maintainers.key''' + OK + vyatta@vyatta:~$ + +Next, we can add the VyOS image. + +Note that Vyatta doesn't support HTTP redirects for **add system image** and the http://mirror.vyos.net HTTP load-balancer links will not work.
