 # Upgrade guidelines
 
+## <0.35.0 to 0.35.0
+OpenTelemetry Operator [0.82.0](https://github.com/open-telemetry/opentelemetry-operator/releases/tag/v0.82.0) includes a change that allows setting the management state of custom resources [PR 1888](https://github.com/open-telemetry/opentelemetry-operator/pull/1888). Since helm doesn't upgrade CRDs ([documented](https://github.com/open-telemetry/opentelemetry-helm-charts/tree/main/charts/opentelemetry-operator#upgrade-chart)) it is critical to manually update CRDs from chart `0.35.0` or above, possibly using [this procedure](https://github.com/open-telemetry/opentelemetry-helm-charts/issues/69#issuecomment-1567285625).  If this step isn't taken existing otelcol CRs won't be reconciled by the operator.
