 Error: VPA updateMode cannot be 'Auto'
 ```
 
+**Why updateMode: Auto is no longer supported:**
+
+The `updateMode: Auto` is no longer supported (considered deprecated) because in the upstream `Vertical Pod Autoscaler`, this mode has been deprecated since `VPA 1.4.0` and is now an alias for `Recreate` - that is, it always works through eviction/recreation of Pods and does not provide the advantages of in-place resizing. 
+In `Deckhouse`, this has been fixed with a change: all `Deckhouse-managed VPAs` have been switched from `Auto` to `InPlaceOrRecreate` so that, if Kubernetes support is available, in-place resource updates are performed, and if it is not available, a fallback to eviction is performed. 
+
+**Which mode to use instead of Auto**
+
+Use `InPlaceOrRecreate` — the preferred mode: it attempts to update resources without restarting the Pod and falls back to eviction (`Recreate`) if necessary. 
+Use `Recreate` if you only need an eviction-based approach and are consciously prepared for Pod restarts. 
+`Off` and `Initial` remain unchanged.
+
+See [PR 17011](https://github.com/deckhouse/deckhouse/pull/17011) for more details.

 ✅ **Correct** - Deployment with proper VPA:
