I am new to this Forum and I read a lot of things that gave me thought-provoking impulses how we can optimize our infrastructure.
However, currently I have two problems where I need your help.
I am in charge of a large vSphere test environment containing several encapsulated ‘testrooms’ with about 9000 VMs and 500 Vyatta/Vyos routers. The old Vyatta (VC6.2)/VyOS(1.1.7) systems finally need to be replaced.
In one of our next maintenance windows we want to shut down all remaining Vyatta routers and migrate them to the latest VyOS version.
We tried this with a configuration export/import, but unfortunately we noticed that not all settings are transferred because of changed commands.
Is there a way to automate this or is there even a “Migration Tool” for this?
- We have built ourselves transfer networks, allowing special services from the test environments to communicate externally.
For this purpose there is a superordinate vyos router/firewall that provides the connection to the outside and a second configured router for the connection between the transfer network and the testrooms that is cloned into the test room.
But since we have to change the MAC address during the cloning proces, the new router loses the configuration of eth0 and eth1 on startup and creates new interfaces eth2 and eth3.
Is there a workaround for this?
