Upgrade prerequisites for all Unica products
Meet all requirements for permissions, operating system, and knowledge correctly before you upgrade Platform to ensure a seamless upgrade experience.
Removing response files generated by previous installations
If you are upgrading from a version before 8.6.0, you must delete the response files that are generated by previous Unica Platform installations. Old response files are not compatible with the 8.6.0 and later installers.
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 file is named installer.properties.
The response files for each product are named installer_productversion.properties.
The installer creates response files in the directory that you specify during installation. The default location is the home directory of the user.
User account requirement for UNIX™
On UNIX™, the user account that installed the product must complete the upgrade, otherwise the installer fails to detect a previous installation.
32-bit to 64-bit version upgrades
If you are moving from a 32-bit to a 64-bit version of Unica Platform, ensure that you complete the following tasks:
- Ensure that the database client libraries for your product data sources are 64-bit.
- Ensure that all relevant library paths, for example startup or environment scripts, correctly reference the 64-bit versions of your database drivers.
Unloading unused files from memory on AIX®
For installations on AIX®, run the slibclean command that is included with your AIX® installation to unload unused libraries from the memory before you run the installer in the upgrade mode.
Backing up custom files
Before starting the upgrade to Unica 12.1.3, backup all the custom files that exist in the <UNICA_HOME>/jre/ location. If you do not backup the custom files that exist in the <UNICA_HOME>/jre/ location, you will lose the files because the Unica 12.1.3 upgrade deletes the existing jre folder and installs a new jre folder containing Oracle JRE files.
