Upgrade and migrating WebSphere eXtreme Scale v7.1
You can migrate to WebSphere eXtreme Scale v7.1 from previous versions, and you can apply maintenance packages to WebSphere eXtreme Scale v7.1.
To avoid outages, consider the order in which you apply the updates to the servers in the configuration.
- Update 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.
- Migrate to WebSphere eXtreme Scale v7.1
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 the configuration files because they are backward compatible. However, if you changed any of the script files that are shipped with the product, reapply these changes to the updated script files.
- Use the Update Installer to install maintenance packages
Use the IBM Update Installer to update the WebSphere eXtreme Scale environment with various types of maintenance, such as interim fixes, fix packs, and refresh packs.
