Currently we are running with Splunk 6.5.0 (build 59c8927def0f) in our environment with all the servers ( 1Cluster master, 1 Deployment Master, 8 Indexers, 4 Search Heads) getting hosted in Linux box with their respective version(Linux version 2.6.32-696.10.3.el6.x86_64) .
So we are planning to upgrade our Splunk Enterprise to the latest version . Hence kindly let us know whether we need to upgrade to Splunk 6.6 and then we need to plan for an upgrade to Splunk 7.0 or Splunk 7.1 versions. Or can we directly upgrade our Splunk Enterprise from 6.5.0 to 7.0 or might be 7.1?
Can you kindly let us know which one would be the preferred option or recommended one and also highlight the best practices to achieve the same.
We are also eager to know about the Pros and Cons before performing the Upgrade to the latest version. Also kindly provide the steps to upgrade from Splunk 6.5.0 to latest version.
