+## Upgrade process
+
+> [!NOTE]
+> Make sure you are upgrading to one of the Purity versions listed in [Supported Purity Software Versions](#supported-purity-software-versions).
+
+Azure Operator Nexus software does not trigger or manage Purity upgrades. Purity upgrades are supported by Pure Storage and can be triggered either through a Pure engineer assisted process or through a self-service process in the Pure1 management portal.
+
+Full details of both upgrade processes, including the procedures for enabling and using self-service upgrade, are available in [Pure's documentation](https://support.purestorage.com/) (login required). Please contact your Pure support representative for further questions about Purity upgrades.
