Splunk Upgrade from 6.4.3 to 6.5.2 in Linux

Hi All, We are planning to upgrade Splunk from 6.4.3 to 6.5.2 before we upgrade to 7.2 or 7.3 , I can see the installation uses symbolic link to the Splunk version, in our case its splunk-6.4.3 linked to rel rel -> splunk-6.4.3 $SPLUNK_HOME is set to /app/splunk/rel, I believe i need to unlink the symbolic link before the upgrade and run the below command in /app and NOT in /app/splunk folder. Just not sure on this, if someone can shed some light here please. tar -xzf splunk-6.5.2-67571ef4b87d-Linux-x86_64.tgz -C /app Please do let me know if this approach would work. Any help is much appreciated.
