After you create the properties file, open a command prompt to start the silent upgrade.
Open a command prompt.
On Windows, open the command prompt as administrator. If you do not open the command prompt as administrator, the Windows system administrator might encounter issues when accessing files in the Informatica installation directory.
Go to the root of the server installer directory.
Verify that the directory contains the file SilentInput.properties with the upgrade options.
Run the silent upgrade. On Windows, run silentInstall.bat. On UNIX, run silentInstall.sh.
The silent upgrade runs in the background. The process can take a while. The silent upgrade process is complete when the Informatica_<Version>_Services_InstallLog<timestamp>.log is created in the installation directory.
The silent upgrade fails if you incorrectly configure the properties file or if the installation directory is not accessible. If the upgrade fails, view the silent upgrade log file and correct the errors. Then run the silent installer again. The silent upgrade log file name is silentErrorLog.log. The installer creates it in the root directory on Windows and in the user home directory on UNIX.
