Model driven customization framework

A computing system comprises, in one example, an upgrade system configured to detect a user upgrade input indicating that a base version of a computing system is to be upgraded, by applying a set of upgrade changes to the base version, to obtain an upgraded version of the computing system, a difference generation system configured to retrieve a customized version of the base version of the computing system and identify that the customized version corresponds to the base version with customizations applied, a combining engine configured to obtain the customizations applied to the base version and the upgrade changes, and combine the customizations with the upgrade changes to obtain a full set of changes, and a difference application engine configured to apply the full set of changes to the base version of the computing system to obtain a customized, upgraded version of the computing system. 在个示例中，种计算系统包括：升级系统，被配置为检测用户升级输入以获得所述计算系统的升级版本，所述用户升级输入指示所述计算系统的基版本将通过向所述基版本应用升级改变的集合而被升级；差异生成系统，被配置为获取所述计算系统的所述基版本的定制版本并且
