Splunk Migration from existing server to a new server
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
