My current Splunk server crashed and i had setup the new Splunk which is running fine. But i need to move/migrate the Splunk index file from old server to this new server. My both the Splunk version is 6.X
Since, i didnt had any custom datastore configuration, i copied the Splunk index files from $SPLUNK_HOME/var/lib/splunk to new server under same path.
Hurray; its working fine.
