Setting up Version 8.5 coexistence

After installing the WebSphere® Application Server product, you can install it again on the same machine.

Before you begin

Supported configurations:

This topic is about configuration migration, such as migrating deployment managers and federated nodes in a network deployment environment. The Application Migration Toolkit for WebSphere Application Server provides support for migrating applications from previous versions of WebSphere Application Server to the latest product version. For information about migrating applications, read more about the Migration Toolkit.

See Overview of migration, coexistence, and interoperability and Premigration considerations.

About this task

This is not a typical scenario. One of the main goals of multiple-profile support is to minimize the need for scenarios like this. One reason that you might want to install two or more instances of WebSphere Application Server Version 8.5 on the same machine might be a need to have different fix levels of the product on a machine.

Procedure

  1. Use the Installation wizard to install another set of the core product files as described in Installing and configuring your application serving environment.

    Select the new installation option from the Installation wizard panel to install a new instance instead of adding features to the last installation and to install into a separate profile directory.

  2. Use the Profile Management tool or the manageprofiles command to create multiple application-server processes.

    During profile creation using the Profile Management tool, you can specify your port settings. See Managing profiles using the graphical user interface for more information.

    During profile creation, the manageprofiles command can use port values that you specify instead of the default port values. You can use a port file, specify a starting port, or accept the default port values. See manageprofiles command for more information.

  3. If you have a node that you cannot start because of port conflicts, change port assignments to nonconflicting ports in configuration files.
    Use one of the following methods:
    • Use the updatePorts tool to change port settings.

      See Updating ports in an existing profile for more information.

    • Edit the profile_root/config/cells/cell_name/nodes/node_name/serverindex.xml file to change the port settings, or use scripting to change the values.
