I want to upgrade a Splunk device version 3.4.5 build 47883 to version 4.0.11 build 79031.
Can I do a direct upgrade or do I need to upgrade to an earlier version of 4.0.x first?
Yes, you can upgrade directly from 3.x to 4.x. However, please read the documentation before doing so.
I have copied a few links to our documentation on how to upgrade, what to expect, and what to consider before upgrading.
