I have downgraded elk and beats of 8v to 7.17.3v. And all 8v were uninstalled and deleted but beats(metric,packet,winlog) of 8v index templates & Data stream is only coming up in kibana 7.17.3v. It's not showing 7.17.3v beats index templates & Data stream which is currently using.
8v beats were not using now.
can someone help to solve this issue.
