Note: This post is superseded by its new version.

Here is a way to silently upgrade from IBM Content Navigator 2.0.3 to 2.0.3 FP5. You can use this right after using the CPIT installer to be up-to-date with your ICN version. You need at least ICN 2.0.3.0 to upgrade to ICN 2.0.3 FP5.

In the same folder you copied 2.0.3-ICN-FP005-LINUX.tar, execute these commands:

# The profile used when installing ICN 2.0.3, if you use the CPIT installer it should already be correct
export profilePath=/opt/IBM/cpit/install-scripts/profiles/NexusConfig
# The path of the IBM Content Navigator Configuration and Deployment Tool, if you used the default location to install ICN, that should be correct
export configmgr_cl=/opt/IBM/ECMClient/configure/configmgr_cl
# WebSphere profile path
export was=/opt/IBM/WebSphere/AppServer/profiles/AppSrv01
# WebSphere node
export wasNode=P8Node01
# WebSphere server
export wasServer=server1

mkdir icnfp
tar -xvf 2.0.3-ICN-FP005-LINUX.tar --directory=icnfp
cd icnfp
sed -i "s/LICENSE_ACCEPTED=false/LICENSE_ACCEPTED=true/g" ecmclient_silent_install.txt
./IBM_CONTENT_NAVIGATOR-2.0.3.5-FP005-LINUX.bin -f ecmclient_silent_install.txt


$configmgr_cl execute -task configureicntask -profile $profilePath
$configmgr_cl execute -task rebuildear -profile $profilePath
$configmgr_cl execute -task deployapplication -profile $profilePath

# Delete cache and restart WAS
$was/bin/stopServer.sh $wasServer
rm -rf $was/temp/$wasNode/$wasServer/navigator
rm -rf $was/wstemp/*
$was/bin/startServer.sh $wasServer

It will ask you for your WebSphere administrator username and password when restarting WAS, you can also add the -username and -password options to fully automatize the upgrade
