I have to upgrade a Search Head Cluster from version 6.4.2 to 7.0.0 and I have a doubt:
in https://docs.splunk.com/Documentation/Splunk/7.0.0/DistSearch/UpgradeaSHC there's written:
Starting with version 6.5, you can perform a rolling upgrade. This allows the cluster to continue operating during the upgrade. To use the rolling upgrade process, you must be upgrading from version 6.4 or later.
