Kustomize has deprecated commonLabels, patchesJson6902, and patchesStrategicMerge in favor of new functionalities and patches. This involves using 'labels' to replace commonLabels, applying cautious refactoring with 'patches' instead of patchesJson6902, and handling specific selector issues to ensure proper application behavior. Testing these changes using kustomize build and diff tools is crucial to avoid any deployment surprises, especially since selectors are immutable and might require recreating deployments.
