Copy Function App Config

This PowerShell script copies configuration settings (Application Settings and Connection Strings) from one Azure Function App in one subscription to another Azure Function App in a different subscription. It's designed for scenarios where you need to replicate settings across environments or subscriptions without deploying code.

Usage

To use this script:

1. Ensure Prerequisites:

   • Install PowerShell 5.1 or later.
   • Have access to both the source and target Azure subscriptions with appropriate permissions.

2. Download or Clone the Repository:

   git clone https://github.com/your-github-username/your-repo-name.git
   cd your-repo-name

3. Open PowerShell with Administrative Privileges:

   • Right-click on PowerShell and select "Run as administrator".

4. Run the Script:

   .\Copy-FunctionAppConfig.ps1 `
       -SourceFunctionAppName "func-source-app" `
       -SourceResourceGroupName "source-rg" `
       -SourceSubscriptionId "source-subscription-id" `
       -TargetFunctionAppName "func-target-app" `
       -TargetResourceGroupName "target-rg" `
       -TargetSubscriptionId "target-subscription-id"

   Replace the parameters with your actual Function App names, Resource Group names, and Subscription IDs.

Parameters

• SourceFunctionAppName: The name of the source Azure Function App from which to copy settings.
• SourceResourceGroupName: The resource group name where the source Function App resides.
• SourceSubscriptionId: The Azure Subscription ID of the source Function App.
• TargetFunctionAppName: The name of the target Azure Function App where settings will be applied.
• TargetResourceGroupName: The resource group name where the target Function App resides.
• TargetSubscriptionId: The Azure Subscription ID of the target Function App.

Important Notes

• This script does not create any Azure resources or deploy code. You must manually create the target Function App beforehand.
• Review and update settings carefully: Some settings like AzureWebJobsStorage or Application Insights keys might need environment-specific values.
• Managed Identity: The script does not configure Managed Identity permissions. You need to set these manually after running the script.
• Testing: Ensure to test thoroughly in the target environment.
