Azure Container Apps: Functions on Azure Container Apps V1 retirement

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.

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.
2. Option A: use the Azure Functions on Azure 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.
