Automated rolling upgrade of a search head cluster

[FRTS777]

I'm planning to upgrade a multi-site IDX & SHC environment to version 9.3 and i have question regarding the automated rolling upgrade feature 

https://docs.splunk.com/Documentation/Splunk/9.3.0/DistSearch/AutomatedSHCrollingupgrade

With the "Automated rolling upgrade of a search head cluster" feature there is the option to execute this on:

• For cluster upgrade, you can run these operations on any cluster member.
• For deployer upgrade, you must run these operation on the deployer.
• For non-clustered upgrade, which means upgrading search heads that are not a part of a search head cluster, you must run these operations on each single search head.

Is it also possible to use this feature to upgrade CM, LM, MC, DS & HFW as part of non-clustered upgrade?

There is an option to execute on Deployer and License Manager,  so i assume i can also use it on the other (stand-alone) management nodes.

Any help would be much appreciated

This documentation is confusing. First it says about automating the rolling upgrade of SHC, then it lists upgrading standalone SH as a use case.

To be honest, I'd avoid using this app. If not for any other reason, it supports only using tgz archive to replace the running splunk instance whereas I tend to use system packages (rpm or deb) whenever possible.

From 9.3 you can also perform automated indexer cluster upgrade. Als in this doc there is a reference to upgrade LM & CM with the app, but they don't mention any other stand-alone servers.
