Create a directory and copy the patch zip file (clause #1) and the configuration file CLI_Update.zip (clause #2) into it.
Extract the CLI_Update.zip file.
The package contains one script for Windows deployments (applyPatch.bat) and one for Linux deployments (applyPatch.sh): Edit the correct file based on your environment (applyPatch.sh for Linux and applyPatch.bat for Windows) - the file contains all the configuration commands which will be executed in order to upgrade the environment (see the READ_ME for details about the parameters). Replace all the relevant placeholders with the correct details of your environment.
Execute the applyPatch.sh / applyPatch.bat script.
Verify at PortX > System > About that the update is listed and the installed version is updated.
