This task describes how to install a V6 product to coexist with another installation instance of V5.x.

Each installation of the base product is a stand-alone Application Server (server1) with its own set of unique configuration files.

Each installation of the Network Deployment product can be a stand-alone deployment manager (dmgr) with its own set of unique configuration files for its cell, a managed node, or a stand-alone Application Server.

The Using the Profile creation wizard topic describes installing the base WebSphere Application Server product or the Network Deployment product once and creating multiple profiles.

Use the following procedure to install multiple installation instances.

 

Procedure

  1. Use the installation wizard to install another installation.

    If you intend to share a single Web server among installations, install the appropriate Version 6 Web server plug-in using the standalone Web server plug-in installation wizard that is provided on a separate CD from the WAS Installation CD.

  2. Share a Web server among multiple installation instances.

    1. Use the Plug-in Installation wizard to select a Web server plug-in.

    2. Use the administrative console to generate the plug-in configuration files for every installation instance and to then merge them into one master configuration.

    3. Use the administrative console to replace the original plugin-cfg.xml file with the master file on the Web server.

    You can access samples from only one of the installation instances.

  3. Change port assignments in configuration files if you have a node that you cannot start because of port conflicts.

 

What to do next

Return to Migrating and coexisting to continue.
