3. WAS各版本之间差异
应用程序的迁移指的是把适用于低版本的 WebSphere 应用服务器的应用程序迁移到高版本的 WebSphere 应用服务器上。随着 J2EE 标准的演进，各个规范版本的升级以及新规范或者编程模型的引入，WebSphere 应用服务器需要向前兼容这些升级的或者新引入的规范以及各种编程模型，同时，对于正确运行在 WebSphere 应用服务器较低版本上的应用程序，亦要求 WebSphere 应用服务器能做到一定程度上的向后兼容。但是，由于标准演化的复杂性，以及 WebSphere 应用服务器本身的 Web 容器或者 EJB 容器的升级，并不是所有的适用于低版本的应用程序都能无缝的迁移到任何一个高版本之上，也需要对应用程序做一些处理。
