How to Upgrade Search Head Cluster members from 6.2.1 to 6.2.2?
There is yet no published instructions for upgrading a search head cluster. For now you may use the following.
a. Stop all cluster members.
b. Upgrade all members.
c. Stop the deployer.
d. Upgrade the deployer.
e. Restart the deployer.
f. Restart the members.
g. Wait one to two minutes for captain election to complete. The cluster will then start functioning.

• You can run SHC members against 5.x or 6.x search peers, so it is not necessary to upgrade the indexers at the same time
