Can I upgrade a search head cluster by a rolling upgrade?

Explorer

Hello Community,

I want to upgrade an indexer cluster and a search head cluster from 6.3.3 to 6.3.4.
From Splunk docs, I could understand that I can upgrade an indexer cluster by a rolling upgrade.

http://docs.splunk.com/Documentation/Splunk/6.3.3/Indexer/Upgradeacluster#Upgrade_to_a_new_maintenan...

But I cannot find information about a search head cluster. Splunk docs only describes upgrading a search head.
Can I upgrade a search head cluster by a rolling upgrade?

As per the same page

Note the following:

 All cluster members must be running the same version of Splunk Enterprise (down to the maintenance level).

So, the in place upgrade is not possible(I infer).

Path Finder

just a side note here, when we have performed the upgrade we had to execute a rolling restart after that.
