This task describes how to install a Version 6 product to coexist with another installation instance of Version 5.x.
Before you begin
After installing the WebSphere Application Server product, you can install it again on the same machine.Why and when to perform this task
Each installation of the base product is a stand-alone Application Server (server1) with its own set of unique configuration files.
When you install any product a second time, the last installation is the one that appears in the registry.
Suppose you have installed three instances of the base WebSphere Application Server product. You use the remove program function of the operating system to uninstall the registered third copy of the base product. A registry record no longer exists that indicates the existence of the other two installation instances. Other applications cannot use a query of the operating system registry to detect the presence of either base WebSphere Application Server product instance.
The Using the Profile creation wizard topic describes installing the base WebSphere Application Server product once and creating multiple profiles.
Use the following procedure to install multiple installation instances.
