@siemless This may be best to discuss in the Slack Users but I could not find you so I will respond here. In some cases, I have boxes where the /opt/splunk dir is mounted to a separate drive w/ mount point /opt/splunk. In that case you can just swap the disk, I learned this method from AWS support. But that takes preplanning. In some cases, I have boxes that are jacked up, either volume issues across multiple disks or just not setup to swap disks. In that case you can use the Splunk docs >>> https://docs.splunk.com/Documentation/Splunk/9.2.1/Installation/MigrateaSplunkinstance I argued with Splunk about the documentation steps but they claim the steps are correct, although I still believe confusing. FWIW this is what I did... 1 >Create a new host with new OS (in my case I rename /re-IP to the original afterward). 2 > Install the same version of Splunk on new host (I used a .tar), set systemd, set same admin pwd, then stop Splunkd, maybe test a restart and reboot, to verify. 3 > Stop Splunkd on old host, tar up /opt/splunk, copy over the old.tar to new box, untar over the new install, then start Splunkd. That worked for me, and going fwd all new hosts will be configured for the disk-swappable process. Good luck
