Where can I check Splunk Search Head compatibility with Indexers ?

[damode]

I have Splunk Search Head version 6.5.2 with ES 4.5.2.
I am planning to install Indexers of 7.3.x version. My plan is to eventually upgrade Splunk Search Head as well, however, first I would like to check compatibility between Search Head and Indexer.

I have searched alot but haven't found any documentation for this.
Please advise.

It's all in the docs. 😉

"While there is some range in compatibility between various Splunk software components, they work best when they are all at a specific version."

https://docs.splunk.com/Documentation/Splunk/7.3.2/DistSearch/Distsearchsystemrequirements

"The search head must be at the same or a higher level than the search peers."

If your indexer tier is clustered check this:

Also, don't forget to check compatibility between you SHs and ES.
