Azure Functions is a serverless compute service from Microsoft Azure. With Azure Functions, you can easily create and deploy small pieces of code that are triggered by events such as HTTP requests, messages in queues, and timer schedules. This blog will cover various topics related to Azure Functions, including how to create, deploy, and manage functions, as well as best practices and use cases for this powerful cloud computing technology.

Azure | How to Migrate from Consumption Plan to App Service Plan
Change Function app hosting plan
How to Migrate from Consumption Plan
to App Service Plan
How to Migrate from Consumption Plan to Premium Plan
Issue:
- I
want to change my consumption plan to app service plan.
- I
want to change my app service plan to consumption plan.
- Is
there any way to change Azure function hosting plans?
Solution:
Azure Functions is a popular serverless computing platform that allows developers to write and run event-driven functions in the cloud. Azure Functions hosting plan migration refers to the process of moving your Azure Functions from one hosting plan to another. In this blog, we will explore the reasons for hosting plan migration, the different types of hosting plans available, and the steps involved in migrating your Azure Functions to a new hosting plan.
Reasons for Hosting Plan Migration,
There are several reasons why you may want to migrate your Azure Functions to a new hosting plan. Some common reasons include:
- Performance: If you're experiencing performance issues with your current hosting plan, you may want to migrate to a higher-performance plan to improve the speed and reliability of your functions.
- Cost: If you're looking to save costs on your Azure Functions, you may want to migrate to a lower-cost hosting plan.
- Scaling: If you're expecting increased traffic or usage for your Azure Functions, you may want to migrate to a hosting plan that supports higher scalability.
There are 3 types of hosting
plan available from function app,
- Consumption plan
- Dedicated App service plan
- Premium plan
Each plan has its own advantage and limitation. You should choose it carefully.
You may see lot of articles and blog which suggest you can change function app hosting plan from consumption to dedicated App Service plan and you will be able to achieve that also, but according to Microsoft recommendation, You should never do this. Your function app will be messed up and you will see a lot of issues.
This has been mentioned on Microsoft Official documentation.
You can switch
between Consumption and Premium plans by
changing the plan property of the function app resource.
But You can't change consumption plan to Dedicated App Service plan or vice versa.
Ref: https://docs.microsoft.com/en-us/azure/azure-functions/functions-scale
Now we know we can
migrate consumption to App service plan hence we should focus on, how to
achieve it.
Steps to change function app from consumption to premium,
- Create the premium plan.
- Then update the plan property of the function app so it no longer points to the consumption plan but the premium one.
- This feature is not available in UI right now
- You can use CLI command for this,
az functionapp update --name MyFunctionApp --plan
<plan name or plan-resource-id>”
|
CLI Ref: https://docs.microsoft.com/en-us/cli/azure/functionapp?view=azure-cli-latest#az-functionapp-update
The premium plan is supported
in some regions only. you can get the list of regions in the below URL if you
face any region issue.
https://docs.microsoft.com/en-us/azure/azure-functions/functions-premium-plan#regions
I observed some limitation as of now e.g. It only worked when,
- Both plans are in the same region.
- Both plans are in the same resource group.
More info : https://github.com/Azure/Azure-Functions/issues/1194
For the dedicated app service plan, the only option is: You should create a new function app in different hosting plan and update/deploy your code.
Please don’t try to change function app hosting plan from consumption to Dedicated App Service plan or vice versa. This may be possible in future but not now.
