Splunk Migration from existing server to a new server

kvm

Hi,

I have a requirement to upgrade RHEL from version 7.9 to 8.X, and our infrastructure team is currently in the process of building a new set of servers running on RHEL 8.X. Consequently, I will need to migrate Splunk from the existing RHEL OS 7.9 to 8.X.

Our Splunk architecture is on-premise and includes multiple Search Heads (SHs) in a cluster, Indexers in a cluster, and various other components.

Has anyone here performed a migration from one OS to another version of the same OS before? Could I please get some guidelines on how to perform this, especially concerning clustered components?

 

I have checked the below steps:

  • Stop Splunk Enterprise services
  • Copy the entire contents of the $SPLUNK_HOME directory from the old host to the new host.
  • Install Splunk Enterprise on the new host.
  • Start Splunk Enterprise on the new instance.

and specifically looking for the any additional steps that need to be performed, particularly for clustered components.

Thank you.

Kiran
