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.
Notes:
• All SHC members must be running the same version (down to the maintenance level).
• 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
