Splunk: How to backup/restore Splunk's data?

[htkwan]

Hello,
Pls advise how one can backup from an existing splunk (7.0) and restore the saved splunk's data to another new splunk (latest version). I can schedule a shutdown for the backup/restore. Thanks

Hi @htkwan,
if you want to upgrade an existing installation, you could backup your data and installation for sure and then upgrade your Splunk installation to the new version.
If instead you want to copy installation to a new instance, make restore of the backupped instace (changing hostnames) and then upgrade to the latest version.
In other words, the best approach is to make backup and restore of the old versione and to leave Splunk automatic procedure to upgrade installation.
You could also copy some file of $SPLUNK_HOME/etc from the old to the new installation, but I don't like it!

Ciao.
