Upgrade of a Search Head Cluster (v6.4.2 > 7.0.0) - Can I do a rolling upgrade?

Hi at all,
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.

It's not so clear for me if I can perform a rolling upgrade from 6.4.2 to 7.0.0 or I must before upgrade from 6.4.2 to 6.5 (not rolling upgrade) and after I can perform the rolling upgrade to 7.0.0.

Anyone has already performed this upgrade?

bye.
Giuseppe

The documentation states that you can perform a rolling upgrade, as long as you are upgrading from version 6.4 or later.

So, yes, you can perform a rolling upgrade from 6.4.2 to 7.0.0.

Why it's written before starting 6.5 and then 6.4?

It means that you can do a rolling upgrade if you are upgrading to 6.5 or later. What it's saying, in total, is that there are two conditions necessary for performing a rolling upgrade:

  • You must be upgrading from 6.4 or later.
  • You must be upgrading to 6.5 or later.
