Hello @Ding, Jianhua | MPB

If you're receiving this email, it is because a function app within in your subscription has been identified as using a registered extension bundle that will soon be deprecated. This function app and/or associated trigger may have already been removed. However, to mitigate the issue, you can refer to the documentation on Migrate Azure Cosmos DB extension for Azure Functions to version 4.x | Microsoft Learn. Just click the tab to match the runtime you're function app is using.

As for identifying function apps, you can use the following PowerShell script, that don't have the extension runtime set to 4.x

$FunctionApps = Get-AzFunctionApp
$FunctionApps | Sort-Object { $_.Name } | Where-Object { $_.ApplicationSettings["FUNCTIONS_EXTENSION_VERSION"] -ne "~4" }
