Hi
here is the supported paths to update to the latest versions. https://docs.splunk.com/Documentation/Splunk/latest/Installation/HowtoupgradeSplunk
Currently the newest version is 9.0.1, but based on that “one over” policy also 8.2 -> 9.1 should agreed option.

I did see that document but was trying to be more careful, since it didn't say I could go directly from 8.2.6 to 9.1.0. Guess, I will do a two steps upgrade.
As there is no 8.3 version you could go directly from 8.2.x to 9.1.x when it comes out sometime on next year. That will be valid way unless Splunk change their policy. On clustered environments you should/could do a live update “without service breaks”.
When they release 9.1 that will be told on installation guide.
Yes, it can. Be sure to consult the Release Notes for any actions required as part of the upgrade.
