Coexist

Expand Migrating, coexisting, and interoperating > Coexisting in the information center navigation to obtain instructions for various coexistence scenarios. Coexistence, as it applies to WebSphere Application Server products, is the ability of multiple installations of WebSphere Application Server to run on the same machine at the same time. Multiple installations include multiple versions and multiple instances of one version. Coexistence also implies various combinations of Web server interaction.

--------------------------------------------------------------------------

Check mark Review supported coexistence scenarios

All combinations of V4.x products, V5.x products, and V6.0 products can coexist so long as there are no port conflicts. There are some coexistence limitations for V5 products that have the embedded messaging feature installed, as described in the documentation.

Check mark Obtain valid port settings for coexistence

Version 6 autonomically detects free ports among profiles installed from the same core product files. The port mechanism does not detect ports in use by previous versions or by other products. You must verify that you are using ports that do not conflict with other products and programs running on your node.

Select free ports on ports selection panel of the Profile creation wizard.

Or, select free ports on ports selection panel of the installation wizard.
