I am setting up parallel Splunk environment of my existing setup what is best approach for data backup?

[vikas_gopal]

Hi Experts,

I have 8 server setup (2 indexers in cluster, 3 SH, 1 CM, 1 Deplyer,LM,1 DS) on splunk 6.5. This setup is migrating as the servers will be decommissioned. So I have to migrate existing setup to not only new splunk version but also all data to the new setup on new servers . My biggest concern is on the data that resides on the existing setup

--> How I will take backup of my existing indexer cluster and restore it in new setup ?
--> Will taking backup of hot/warm/cold/frozen and put these backups on the new splunk setup under data location using 6.5 and after restore I will upgrade to 7.6 is it a good approach ?
--> Do I need to stop indexers and take backup of only one indexer and then take that to new machines ? OR both the indexer backup is required . I wonder both indexer data is duplicate data .

I have checked splunk docs to take data backup like https://docs.splunk.com/Documentation/Splunk/7.1.2/Indexer/Backupindexeddata but I am still not sure for cluster backup.

Regards
VG

You have to follow the process to upgrade on the buckets prior to migration OR you have to start with 6.5 on the new servers and follow the upgrade path there.

Since upgrading a clustered environment requires a special process, you should follow the docs.

https://docs.splunk.com/Documentation/Splunk/8.0.1/Installation/HowtoupgradeSplunk

There's really no great method to backup splunk. Instead I would stand up the new servers as a new site, point everything at the new servers, then shut down the old cluster when the data is no longer needed.

This would be an intricate process, and I would highly recommend professional services for something like that/this.
