We have 3 Indexers, 2 Search Heads, 1 Master Indexer/License Master/Deployment server all instances working on 6.3.
We are planning to upgrade Splunk to 6.5, but for initial stage we are planning to go with an upgrade only for Master Indexer which is a license master as well for us and later rest of the servers can be upgraded.
Please suggest if any plan we can go ahead with to get the infra upgraded to 6.5 Splunk or the entire cluster needs to be upgraded at once.
Thanks.
Vikram,.
