Migrating to WebSphere eXtreme ScaleVersion 8.6

With the WebSphere® eXtreme Scale installer, you cannot upgrade or modify a previous installation. You must uninstall the previous version before you install the new version. You do not need to migrate your configuration files because they are backward compatible. However, if you changed any of the script files that are shipped with the product, you must reapply these changes to the updated script files.

Before you begin

Verify that your systems meet the minimum requirements for the product versions you plan to migrate and install. See Hardware and software requirements for more information.

About this task

Merge any modified product script files with new product script files in the /bin directory to maintain your changes.

Tip: If you did not modify the script files that are installed with the product, you are not required to complete the following migration steps. Instead, you can upgrade to Version 8.6 by uninstalling the previous version and installing the new version in the same directory.
