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.

Procedure
- 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.
- 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.
- If you have a node that you cannot start because of port
conflicts, change port assignments to nonconflicting ports in configuration
files.
