We have 1 indexer, 1 SH and 1 DS . We are planning for an OS upgrade (OS RHEL 6 to OL 7) .All the these devices are on the Cloud . Can someone help me what are the steps to be taken from Splunk perspective during this upgrade . What are the checks to be done and is there any pattern like first indexer , then DS and then SH to be followed .
What to do in a fail over .
Splunk is not getting upgraded as of now . We are keeping the same splunk version 7.3.
