Theme Upgrade to Higher versions


I'M shah from caxid technologies .We are building cs-cart templates in which we have a query

For eg : We have a template built for Cs-cart version 2.2.1 , now the 2.2.2. version has been released the template for this version we have to perform a manual theme upgrade for this version .Can you please tell me any other ways to upgrade the theme rather than doing manual upgrade .If there are any methods please let me know so we can satisfy cs-cart clients in a faster and quality way

Thanks .Expecting your suggestions
