To upgrade the Informatica services without user interaction, upgrade in silent mode. Use a properties file to specify the upgrade options. The installer reads the file to determine the upgrade options. You can use silent mode upgrade to upgrade the Informatica services on multiple machines on the network or to standardize the upgrade process across machines.
Copy the Informatica installation files to the hard disk on the machine that hosts the Informatica instance you plan to upgrade.
To upgrade in silent mode, complete the following tasks:
Create the upgrade properties file and specify the upgrade options.
Run the installer with the upgrade properties file.
Secure the passwords in the upgrade properties file.
