patches:
  - target:
      group: apps
      version: v1

🛠 Migration Steps

Replace patchesStrategicMerge with patches.
Move apiVersion, kind, and metadata.name into a target: block.
Keep only the changed content (e.g., spec, metadata) inside patch:.
Maintain proper indentation and valid YAML syntax.
