Installation is an easier, more consistent, and functionally rich experience across platforms, installable components, and types of installations.
The Version 8.0 Centralized Installation Manager (CIM) can be used to manage Version 8.0 and previous versions of WebSphere Application Server. You can use CIM to install or uninstall Version 8.0 and previous versions of WebSphere Application Server on remote machines and apply maintenance from the administrative console. In Version 8.0, targets can now be added outside of the cell. The process for managing Version 7.0 and previous versions is different from the process for managing Version 8.0, and each process is documented separately in the information center.
