Current Behavior or Linked Issues

AKS 1.25.x will EOS next year January, we are already behind schedule if we want to need to check whether will be any issues with recent AKS versions such as 1.27
Upgrading 2 major versions as k8s it is being deprecated fast, 1.27 it is scheduled to EOS on July 2024.
KEDA needs to be upgraded to avoid warns about upgrade.

Does this introduce a breaking change?

[NO]

Provided instructions on how to avoid downtime, if the proper surge for nodes it is configured, there should not be any downtime, moreover, AKS it is more stable and faster than ever, it took me about ~30m to upgrade our internal cluster by using azure web ui, not terraform.
By using terraform it might take more than 1hr in my experience, however, the upgrade should go smoothly with current Azure-osdu configuration.
