Today we are announcing the upcoming retirement of the Azure Sphere Legacy service interfaces, including the Azure Sphere (Legacy) API (also known as PAPI), and the Azure Sphere (Legacy) CLI (also known as azsphere), on September 27th, 2027. Before this date, you must migrate from Azure Sphere (Legacy) to Azure Sphere (Integrated). Azure Sphere (Legacy) will remain fully supported until the retirement date.
Azure Sphere (Integrated) supports all Azure Sphere (Legacy) features, and enables you to use other powerful Azure services when managing your Azure Sphere devices, including Microsoft Entra ID, Azure role-based access control, and Azure Monitor.
From now through September 27th, 2027, Azure Sphere (Legacy) will be fully supported, and you can continue to use the Azure Sphere (Legacy) API and CLI interfaces. However, by September 27th, 2027, you must migrate to Azure Sphere (Integrated) and start managing your Azure Sphere devices in Azure portal and the Azure CLI, and you must update any custom automation and applications to use the Azure Sphere (Integrated) API. After September 27th, 2027, you will no longer be able to manage your Azure Sphere devices using the Azure Sphere (Legacy) API and CLI interfaces.
