The Functions on Azure Container Apps (ACA) V1 will be retired on September 29, 2027. After this date, existing Functions on ACA V1 Apps will stop running and no longer process
requests or event-driven triggers.
Action required
Review your Azure environments and migrate all affected apps
to the Functions on Azure Container Apps(ACA) V2 hosting model before September 29, 2027 to avoid service
disruption.
Functions on ACA V2 uses a native Azure Container App configured
with `kind=functionapp`. You can reuse your existing container image; the
standard migration path doesn't require function code changes.
Use the Azure
Functions on Azure Container Apps v1 migration assistant to help
migrate your function apps from the V1 to V2 model.
To migrate manually
1. Record the V1 app's configuration, including secrets,
identity, networking, and scaling.
2. Create a V2 app with `kind=functionapp` and reapply the
configuration.
3. Test all triggers, shift production traffic, and then
decommission the V1 app.
We recommend completing migration and production
validation well before the retirement date.
