Cloud service (extended support) expired (until March 2027)

Hi 髙村 陸, Welcome to Microsoft Q&A

You're receiving this notice because you're using Azure Cloud Services (Extended Support), which is scheduled for retirement on March 31, 2027. To avoid service interruptions, Microsoft recommends migrating your workloads to Service Fabric Managed Clusters (SFMC).

What Should You Do?

1. Evaluate Your Current Deployment

Review all your Cloud Services (Extended Support) resources in the Azure Portal.

Identify which apps or workloads need to be migrated.

2. Decide on Migration Target

You have two main options:

Service Fabric Managed Clusters (SFMC) – Microsoft's recommended path for most Cloud Services (ES) workloads.

Alternatively, consider Azure App Service, Azure Kubernetes Service (AKS), or Azure Virtual Machines depending on your architecture and goals.

3. Plan the Migration

Microsoft offers detailed migration guidance here.

Migration overview steps:

Export your existing service definition and configuration files.

Repackage or containerize your app (optional but encouraged).

Deploy to SFMC using ARM templates or Bicep.

4. Test Before Cutover

Spin up your Service Fabric cluster in parallel.

Deploy and validate app behavior before retiring the existing Cloud Service.
