When you run the installer, you can choose the upgrade options and actions based on your current installation. When you choose a product to upgrade, the installer upgrades parent products as needed, and either installs or upgrades the product that you choose.

For example, if you choose Enterprise Data Catalog, the installer will upgrade the domain if it is running a previous version. If Enterprise Data Catalog is installed, the installer will upgrade it. If Enterprise Data Catalog is not installed, the installer will install it.

The unified installer is enhanced to perform the following tasks:

Create a separate monitoring Model Repository Service when you install Informatica domain services.
Tune the Data Integration Service and the Model Repository Service based on the Big Data Management deployment size.
Create a cluster configuration and associated connections required by the Enterprise Data Lake.
Enables the Data Preparation Service for Enterprise Data Lake.

The installer includes big data products only. It does not include traditional products such as PowerCenter and Informatica Data Quality. The traditional products and big data products are on separate release trains. If you are upgrading, and the domain includes traditional and big data products, you must split the domain before you upgrade.
