# Azure Container Apps: Functions on Azure Container Apps V1 retirement

Retirement date for Functions on Azure Container Apps V1: 29 Sep 2027. After that date, existing V1 apps stop running and no longer process requests or event-driven triggers.

- Effective date: 29 Sep 2027
- Cloud: [Azure](https://eolwatch.dev/cloud/azure.md)
- Service: [Azure Container Apps](https://eolwatch.dev/services/azure/container-apps.md)
- Type: Retirement
- Category: [Feature](https://eolwatch.dev/categories/features.md)

- Announced: 29 Sep 2026
- Official source: [azure.microsoft.com](https://azure.microsoft.com/updates?id=570800)
- Last checked: 12 Nov 2026

## What breaks

After the retirement date, existing Functions on Azure Container Apps V1 apps stop running and no longer process requests or event-driven triggers. Functions on Azure Container Apps V2 uses a native Azure Container App configured with `kind=functionapp`. The existing container image can be reused, and the standard migration path does not require function code changes.

## Who is affected

### Affected versions

- `V1`

## What to do

1. Review your Azure environments and migrate all affected apps to the Functions on Azure Container Apps V2 hosting model before the retirement date. See [Migrate to Azure Functions v2 on Azure Container Apps](https://learn.microsoft.com/azure/container-apps/migrate-functions).
2. Option A: use the [Azure Functions on Azure Container Apps v1 migration assistant](https://github.com/Azure-Samples/functions-on-container-apps-v1-migration-assistant) to help migrate function apps from the V1 to the V2 model.
3. Option B, manual: record the V1 app's configuration, including secrets, identity, networking, and scaling.
4. Manual: create a V2 app with `kind=functionapp` and reapply the configuration.
5. Manual: test all triggers, shift production traffic, and then decommission the V1 app.
6. Complete migration and production validation before the retirement date.

## Replacement

Functions on Azure Container Apps V2
