Migrate from Vyatta Core¶
VyOS 1.x.x line aims to preserve backward compatibility and provide a safe upgrade ath for existing Vyatta Core users. 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.
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.
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
vyatta@vyatta:~$ '''wget http://vyos.net/so3group_maintainers.key''' Connecting to vyos.net (x.x.x.x: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.
This example uses 1.0.0 image, however, it’s better to install the latest release.
vyatta@vyatta:~$ show system image The system currently has the following image(s) installed: 1: VC6.6R1 (default boot) (running image) vyatta@vyatta:~$ add system image http://0.uk.mirrors.vyos.net/iso/release/1.0.0/vyos-1.0.0-amd64.iso Trying to fetch ISO file from http://0.uk.mirrors.vyos.net/iso/release/1.0.0/vyos-1.0.0-amd64.iso % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 223M 100 223M 0 0 960k 0 0:03:57 0:03:57 --:--:-- 657k ISO download succeeded.

Upon reboot, you should have a working installation of VyOS.
You can go back to your Vyatta install using the
set system image default-boot
command and selecting the your previous Vyatta image.
Future releases of VyOS will break the direct upgrade path from Vyatta core. Please upgrade through an intermediate VyOS version e.g. VyOS 1.2.x.
