You can migrate to Version 8.6 from previous versions, or you
can apply maintenance packages. To avoid
outages, you must consider the order in which you apply the updates
to the servers in your configuration.
Updating eXtreme Scale servers
You can upgrade WebSphere® eXtreme Scale to a new version, either by applying maintenance or installing
a new version, without interrupting service.
Migrating to WebSphere eXtreme Scale Version 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.
Installing fix packs using IBM Installation Manager
You can use IBM® Installation
Manager to update the product with the fix packs that are available
for WebSphere eXtreme Scale product
offerings. Fix packs can be installed from the GUI, the command line,
or using response files.
Uninstalling fix packs using IBM Installation Manager
You can use IBM Installation
Manager to rollback WebSphere eXtreme Scale product offerings to an earlier version.
You can uninstall fix packs from the GUI, the command line, or using
response files.
Upgrading WebSphere eXtreme Scale Client for .NET
You can upgrade an existing WebSphere eXtreme Scale Client for .NET installation by
running the installation program. The program detects the existing
installation and replaces the appropriate files.
