# Azure Sphere: Legacy API and CLI interfaces retirement

Retirement date for the Azure Sphere Legacy service interfaces, including the Azure Sphere (Legacy) API (PAPI) and the Azure Sphere (Legacy) CLI (azsphere): 27 Sep 2027. Device management moves to Azure Sphere (Integrated).

- Effective date: 27 Sep 2027
- Cloud: [Azure](https://eolwatch.dev/cloud/azure.md)
- Service: [Azure Sphere](https://eolwatch.dev/services/azure/sphere.md)
- Type: Retirement
- Category: [API or SDK](https://eolwatch.dev/categories/apis-sdks.md)
- Replacement: Azure Sphere (Integrated)
- Announced: 3 Oct 2024
- Official source: [azure.microsoft.com](https://azure.microsoft.com/updates?id=azure-sphere-legacy-interface-retirement)
- Last checked: 12 Nov 2026

## What breaks

After the retirement date, Azure Sphere devices can no longer be managed with the Azure Sphere (Legacy) API and CLI interfaces. This covers the Azure Sphere (Legacy) API, also known as PAPI, and the Azure Sphere (Legacy) CLI, also known as azsphere. Until the retirement date, Azure Sphere (Legacy) is fully supported. Azure Sphere (Integrated) supports all Azure Sphere (Legacy) features.

## What to do

1. Migrate from Azure Sphere (Legacy) to Azure Sphere (Integrated) before the retirement date.
2. Manage Azure Sphere devices in Azure portal and the Azure CLI.
3. Update custom automation and applications to use the Azure Sphere (Integrated) API.
4. For how to migrate, see [this blog post](https://go.microsoft.com/fwlink/?linkid=2289217).

## Replacement

Azure Sphere (Integrated)
