Is it possible to easily copy applications settings from one web app to another on azure

Question

I was wondering if there is an easy way to completely copy all the key values from one web app's application settings to another, as seen in the below picture I have a lot of these key values and having to do this manually every time is very cumbersome.

You can use Azure PowerShell. Here is a PowerShell Script for you.

try{
    $acct = Get-AzureRmSubscription
}
catch{
    Login-AzureRmAccount
}

$myResourceGroup = '<your resource group>'
$mySite = '<your web app>'
$myResourceGroup2 = '<another resource group>'
$mySite2 = '<another web app>'

$props = (Invoke-AzureRmResourceAction -ResourceGroupName $myResourceGroup `
        -ResourceType Microsoft.Web/sites/Config -Name $mySite/appsettings `
        -Action list -ApiVersion 2015-08-01 -Force).Properties

$hash = @{}
$props | Get-Member -MemberType NoteProperty | % { $hash[$_.Name] = $props.($_.Name) }

Set-AzureRMWebApp -ResourceGroupName $myResourceGroup2 `
        -Name $mySite2 -AppSettings $hash

This script copy app settings from $mySite to $mySite2. If your web app involves with slot, for $props, you should use the following command instead.

$props = (Invoke-AzureRmResourceAction -ResourceGroupName $myResourceGroup `
        -ResourceType Microsoft.Web/sites/slots/Config -Name $mySite/$slot/appsettings `
        -Action list -ApiVersion 2015-08-01 -Force).Properties 

And, use Set-AzureRMWebAppSlot instead of Set-AzureRMWebApp

Set-AzureRMWebAppSlot -ResourceGroupName $myResourceGroup2 `
        -Name $mySite2 -Slot $slot -AppSettings $hash
