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
8.5 by uninstalling
the previous version and installing the new version in the same directory.
