Missing docs: moving from classic to helm mode #1793
Comments
hi @SemaiCZE 👋 unfortunately cilium-cli currently does not support upgrading classic mode installations to helm mode. you could continue to use the classic mode upgrade command, but it was never properly implemented either: Lines 26 to 136 in 0e7c883

Thanks @michi-covalent, it's sad that there is no upgrade path. I was feeling lucky today so I prepared a yaml file with helm values the same way I had it in my notes from previous installation (mainly CIDRs for IPv4 and IPv6 and a few more settings) and then uninstall cilium using cli in classic mode and immediatelly after install it again using helm. It worked better than expected 👍. But some note about this in docs or release notes would be great, even if there is no great solution for people. P.S.: helm also solved this issue (#1911) I had before 🙂 |
that's great to hear! yeah i'm preparing release notes in cilium/cilium#26606 regarding the incompatibility between helm and classic modes 📝 |

Proposal / RFE
Hi, I have a cilium in my k3s cluster and it was installed using cilium-cli (somewhere around v0.13.0 where there was no helm mode available). Now I upgraded to cilium-cli v0.15.0 where the classic mode is deprecated. But using helm mode does not work out of the box:
I can't find anywhere what to do to migrate my installation to helm. A I really don't want to destroy and recreate all of my networking.
Is your feature request related to a problem?
Not yet, but with the future release of cilium-cli I won't be able to upgrade my cluster anymore.
Describe the solution you'd like
I'd like description how to migrate from old installation method to the new helm method.
Thanks,
-Petr
