Use the server installer to upgrade the domain of a previous version of Informatica services. The server installer provides a domain upgrade wizard to guide you through the upgrade process.
The upgrade wizard installs Informatica 10.2.0 HotFix 1 in the installation directory you specify. It does not modify the files in the directory of the previous version.
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 Informatica 10.2.0 HotFix 1. 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. On Windows, you can upgrade in graphical or silent mode. On UNIX, you can upgrade in console or silent mode.
In a multi-node domain, upgrade the master gateway node before you upgrade other nodes.
You can perform the upgrade from the root of the directory where you download the installation files.
After you upgrade the domain, upgrade Informatica Developer to the same Informatica version, including the hotfix version.
