The upgrade wizard reads the domain information from files in the previous version and uses the same settings to configure the domain and server files for the upgrade. It upgrades the tables of the domain configuration repository in the same database as the previous version.
Complete the pre-upgrade tasks before you start the upgrade. Run the installer on all machines that host previous versions of Informatica that you want to upgrade.
In a multi-node domain, upgrade a gateway node before you upgrade other nodes.
You can perform the upgrade from the directory where you downloaded where you download the installation files.
After you upgrade the domain, upgrade the Informatica client tool to the same Informatica version.
