Quickstart: Migrate Linux Consumption apps to Flex Consumption using GitHub Copilot

In this quickstart, use GitHub Copilot with the Azure skills plugin to interactively migrate your Linux function apps from the Consumption plan to the Flex Consumption plan. Copilot automates most of the migration, including assessment, app creation, configuration, deployment, and validation.

Important

This article demonstrates how to use Copilot to recreate an existing Linux Consumption app in a Flex Consumption plan. The Azure skill that Copilot uses to achieve the migration work is designed to work with most Linux Consumption apps. For high-value production apps, apps with complex deployments or dependencies, and for Consumption apps running on Windows, follow Migrate Consumption plan apps to the Flex Consumption plan.

You can review the specific skill used by Copilot when performing this migration in the GitHub Copilot Azure skills repository.

Prerequisites

  • An Azure subscription with one or more Linux function apps running on the Consumption plan.

  • The account used for the migration must have the Owner or Contributor role in the resource group containing your function apps. For the full list of required permissions, see Prerequisites.

  • Azure CLI, version 2.77.0 or later.

  • Configure GitHub Copilot in your preferred mode:

    [!INCLUDE functions-copilot-setup]

Migrate your apps

Use this prompt to start an interactive migration that scans your subscription and lets you choose which apps to migrate:

migrate my linux function apps in azure from consumption to flex consumption

Copilot follows the migration guide and identifies your eligible Linux Consumption apps, lets you choose which ones to migrate, and then handles assessment, app creation, and configuration migration for each app.

You might be asked by Copilot for feedback during the migration, as needed for a successful migration.

Migration results

When complete, Copilot generates helpful output, which includes:

  • A summary table with the status of each migrated app.
  • A brief summary of the overall tasks accomplished.
  • A list of any remaining post-migration tasks that it couldn't complete or that must be done by you.

Verify the migration

While Copilot does its best to validate the state of your migrated app, always verify that your new app works correctly:

  1. In the Azure portal, ensure that each new Flex Consumption app shows a Status of Running.

  2. Call at least one HTTP trigger endpoint or otherwise trigger your new app to confirm it responds as expected.

(Optional) Remove the original app

When you're confident the new app works correctly, remove the original Consumption plan app. If you keep the original app in place, remember to disable any triggers to avoid duplicate processing or competing with the new app.

Use this command to remove the original app:

delete my original consumption app <ORIGINAL_APP_NAME>

Copilot always asks for your explicit confirmation before deleting anything.

Important

Before deleting, make sure you migrate all functionality, verify no traffic goes to the original app, and back up any relevant logs or configuration.
