Our Splunk instance has indexed data from the last 1 year from various servers and is in use currently. Most of the data are indexed into the default 'main' index. Now, we would like to create some users with access to logs only from a particular a set of servers. Is it possible to split the already indexed data from this particular set of servers from the 'main' index to a new index so that I can grant the new users access only to the newly created index?
Have you tried out to use restricted search terms from access controls -> roles for your users?
