End of support date for PowerShell 7.4 on Azure Functions: 10 Nov 2026. Function apps keep running after that date but stop receiving security patches, updates and customer support.

- Cloud: [Azure](https://eolwatch.dev/cloud/azure.md)
- Service: [Azure Functions](https://eolwatch.dev/services/azure/functions.md)

## What breaks

After the end of support date, function apps on PowerShell 7.4 continue to run, but security patches and updates are no longer provided and customer support for PowerShell 7.4 is discontinued. Microsoft states that running function apps on an unsupported runtime or language version may lead to issues and degraded performance. Apps on a Linux Consumption plan must first upgrade to the Flex Consumption plan before upgrading to PowerShell 7.6.

## Who is affected

### Affected versions

- `7.4`

### Matching resource types

- `microsoft.web/sites`
- `azurerm_linux_function_app`
- `azurerm_windows_function_app`

### Fields the check reads

- `linuxfxversion`
- `kind`
- `site_config.application_stack.powershell_core_version`

### Detected by the estate check from

- Azure Resource Graph export (CSV or JSON)
- Terraform state or plan (JSON)
- ARM template

## What to do

1. If the app is on a Linux Consumption plan, upgrade to the Flex Consumption plan first.
2. Upgrade the app to PowerShell 7.6 before 10 Nov 2026. [Follow the steps to upgrade your app](https://learn.microsoft.com/en-us/azure/azure-functions/update-language-versions?tabs=azure-portal%2Cwindows&pivots=programming-language-powershell).
