We are migrating from Splunk 6.3.0 to Splunk 6.4.1.Any configuration changes need to be made? Or all the apps will work properly without any changes?
When you are upgrading to a new version of Splunk Enterprise, you should always check the "About upgrading...READ ME FIRST" topic in the Installation Manual.
For 6.4, it's http://docs.splunk.com/Documentation/Splunk/6.4.1/Installation/Aboutupgradingto6.4READTHISFIRST
