converting Managed solution to Unmanaged solution Work around:
This is useful when we have only Managed solution to work with but needs some more customization. Extract the Solution Zip file, Open solution.xml file in notepad application. Search for Managed Tag (E.g.: <Managed>1</Managed>), Now change the value from 1 to 0 and zip the files again and import it. That’s it The Solution is changed to Unmanaged. This can be imported and customized as per the need.
