Upgrade Support Changes
In version 10.2.1, Informatica supports upgrade for Informatica big data products only, such as Big Data Management and Big Data Quality. When you upgrade the domain, functionality for traditional products such as PowerCenter and Informatica Data Quality will not be available.
If you run traditional and big data products in the same domain, you must split the domain before you upgrade. When you split the domain, you create a copy of the domain so that you can run big data products and traditional products in separate domains. You duplicate the nodes on each machine in the domain. You also duplicate the services that are common to both traditional and big data products. After you split the domain, you can upgrade the domain that runs big data products.
Although Informatica traditional products are not supported in version 10.2.1, the documentation does contain some references to PowerCenter and Metadata Manager services.
