Hey everyone! I'm having a bit of a dilemma. Currently, I have a load balancer that's being used internally in my Azure Kubernetes Service (AKS) setup, which is on version 1.23. I need to upgrade the load balancer from Basic to Standard because of its retirement. However, the official documentation states that I need to be on AKS version 1.27 at least for this upgrade. Unfortunately, due to some constraints, I can't upgrade my AKS. Is there any way to update the load balancer without having to touch the AKS version? Thanks!

It seems like you're stuck because version 1.27 is an LTS release, and you'd need to be on a supported version to switch the load balancer. I'm really curious why you can't upgrade your AKS though! You might want to consider it if possible.
You could opt for an internal load balancer if you're flexible. But really, you should sort out whatever’s holding you back from upgrading—that situation isn’t sustainable in the long run.
Looks like the link you provided was broken! But I've managed to fix it now. Let me know if you need any more info!
Honestly, your AKS version is pretty outdated, and Microsoft will likely push you to upgrade soon. I’d suggest regularly updating the AKS cluster to avoid security risks. If upgrading is not an option at the moment, deploying a new cluster and migrating your workloads with some A/B testing might be the safest bet.
Totally agree with you! The cluster being on an unsupported version isn't ideal, and the documentation you linked is the only way to convert the existing cluster to a Standard SKU load balancer. Setting up a side-by-side cluster ensures you have a backup plan. If your deployment pipeline isn't sturdy, consider using Azure backup for AKS or something like Velero to back up your existing cluster.
