Informatica version 10.5.2 is a hotfix release. You can apply the hotfix to 10.5 or 10.5.1, or you can upgrade from a supported release. You can run the Informatica installer to install 10.5.2 product installation binaries if they are not present in the machine where you run the installer.
Informatica version 10.5.2 supports PowerCenter, Informatica Data Quality, Data Engineering products, Catalog products, Data Privacy Management, and Test Data Management products as part of the unified installer. Test Data Management and Data Privacy Management require an upgrade of services in addition to applying the hotfix.
The instructions to apply the hotfix are the same for all the products, but the pre- and post-requisites are different for the products other than Data Engineering products, Data Quality, and PowerCenter. Refer to those individual upgrade guides for information.
