Copy Azure Permissions

I was replacing an old service account with a service principal, and needed to replicate the permissions in Azure. I was able to do that without missing anything, using the command below.

$CopyFrom = 'Object to copy from'
$CopyTo = 'Object to copy to'
Get-AzRoleAssignment -ObjectId $CopyFrom | ForEach-Object{
    New-AzRoleAssignment -ObjectId $CopyTo -RoleDefinitionId $_.RoleDefinitionId -Scope $_.Scope
}
