Hey everyone! I'm looking to upgrade my edge store K3s clusters, currently running on version v1.23.10+k3s1, to v1.30.10+k3s1. I've read about using system-upgrade, but most resources focus on multi-node setups. I'm managing these clusters with Rancher v2.7.1 and planning to set up a new instance with v2.11.0, aiming to sequentially migrate the clusters. With over 500 K3s clusters to handle, I'm unsure of the best method to approach this upgrade. Any guidance would be appreciated! Thanks!

Honestly, upgrading all those 500 clusters from v1.23 to v1.30 one at a time sounds like a nightmare. I'd recommend creating new clusters and migrating your workloads over. It might mean convincing your management to get the resources you need for this, but it’ll save a ton of headaches during the upgrade!
Thanks for the input! Convincing management is going to be tough, but I might look at setting up a new Rancher and migrating in batches instead. Given we're in edge computing, getting that many servers won't be easy. Appreciate the advice!
