+Upgrade guidelines
+=================================
+
+Apply the following changes to the Collector configuration files for specific version upgrades. For more details refer to :new-page:`Helm chart upgrade guidelines <https://github.com/signalfx/splunk-otel-collector-chart/blob/main/UPGRADING.md>` in GitHub. 
+
+From 0.113.0 to 0.116.0
+---------------------------------------
+
+Custom resource definition (CRD) configuration has been modified. 
+
+* Before v0.110.0 CRDs were deployed via a ``crds/`` directory (upstream default).
+* From v0.110.0 to v1.113.0 CRDs were deployed using Helm templates (upstream default), which had reported issues.
+* From v0.116.0 and higher, you must explicitly configure your preferred CRD deployment method or deploy the CRDs manually to avoid potential issues. You can deploy CRDs via a ``crds/`` directory again by enabling a newly added value.
+
+New users
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+If you're a new user deploy CRDs via the ``crds/`` directory. For a fresh installation use the following Helm values:
+
+.. code-block:: yaml
+
+  operatorcrds:
+    install: true
+  operator:
+    enabled: true
+
+To install the chart run:
+
+.. code-block:: bash
+
+  helm install <release-name> splunk-otel-collector-chart/splunk-otel-collector --set operatorcrds.install=true,operator. enabled=true <extra_args>
+
+Current users 
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+You might need to migrate if using ``operator.enabled=true``.
+
+If you're using versions 0.110.0 to 1.113.0, CRDs are likely deployed via Helm templates. To migrate to the recommended ``crds/`` directory deployment:
+
+1. Delete the existing chart running
+
+  .. code-block:: bash
+
+    helm delete <release-name>
+
+2. Verify if the following CRDs are present and delete them if necessary:
+
+  .. code-block:: bash
+
+    kubectl get crds | grep opentelemetry
+    kubectl delete crd opentelemetrycollectors.opentelemetry.io
+    kubectl delete crd opampbridges.opentelemetry.io
+    kubectl delete crd instrumentations.opentelemetry.io
+
+3. Reinstall the chart with the updated configuration:
+
+  .. code-block:: bash
+
+    helm install <release-name> splunk-otel-collector --set operatorcrds.install=true,operator.enabled=true <extra_args>
+
+Current users maintaining legacy templates
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+If you're using chart versions 0.110.0 to 1.113.0 and prefer to continue deploying CRDs via Helm templates (not recommended), use the following values:
+
+.. code-block:: yaml
+
+  operator:
+    enabled: true
+  operator:
+    crds:
+      create: true
+
+.. caution:: This method might cause race conditions during installation or upgrades.
+
+From 0.105.5 to 0.108.0
+---------------------------------------
+
+.. note:: If you have no customizations under ``.Values.operator.instrumentation.spec.*`` no migration is required.
+
+The Helm chart configuration for operator auto-instrumentation has been simplified, and the values previously under ``.Values.operator.instrumentation.spec.*`` have been moved to ``.Values.instrumentation.*``.
+
+The updated path looks like this:
+
+.. code-block:: yaml
+
+  instrumentation:
+    endpoint: XXX
+    ...
+
+The deprecated path was:
+
+.. code-block:: yaml
+
+  operator:
+    instrumentation:
+      spec:
+        endpoint: XXX
