Upgrade prerequisites for all IBM® EMM products
To upgrade any IBM® EMM product, you must meet all of the prerequisites listed under Prerequisites in the "Preparing to Install" chapter.
In addition, you must meet the prerequisites listed in this section.
Remove response files generated by previous installations
Before you run the installer to upgrade from pre-8.6.0 versions, you must delete any response files generated by previous installations.
Old response files are not compatible with 8.6.0 and later installers because changes were made to installer behavior and response file format.
Failure to remove old response files can result in having incorrect data pre-filled in installer fields when the installer is run, or in the installer failing to install some files or skipping configuration steps.
The response files are named installer_<product><version>.properties, except for the file for the IBM® installer itself, which is named installer.properties. The installer creates these files in the directory specified by the user during installation. The default location is the user's home directory.
User account requirement (UNIX™ only)
On UNIX™, the same user account that installed the product must perform the upgrade.
32-bit to 64-bit version upgrades
If you are moving from a 32-bit to a 64-bit version of an IBM® EMM product, ensure that the following conditions are met.
*
The database client libraries for your product data sources are also 64-bit
*
All relevant library paths (for example, startup or environment scripts) correctly reference the 64-bit versions of your database drivers
Knowledge requirements
These instructions assume that the person performing the upgrade has an understanding of the following areas:
*
The basic function of the IBM® installer, as described in How the IBM EMM installers work
*
General IBM® EMM product functionality and components, including the structure of the file system
*
The installation and configuration process for the source product version and for the new version
*
Maintaining configuration properties in the source and target systems
*
The installation and configuration process for reports, if you are using these reports
