Splunk Migration of Search Head and Deployment Server from old Linux Distro to new Linux Distro

[n3wbi3]

I want to migrate my clustered environment from one Linux to another.

Is it possible to migrate search head and deployment server first and then the indexers on the other day?

CentOS and the new distro is RHEL? Any Ideas or suggestions?

There are many threads about migrating environments in different scenarios. Use the search 🙂

General idea is that your environment should be consistent in terms of used OS and its version but there is no explicit requirement that SH tier must be on the same OS distribution as the indexer-tier (although it is of course best to have a relatively homogenous environment for maintenance reasons) or that the DS must be on the same OS as SHs.

This is the beauty of using DNS CNames to reference all your Splunk servers in configuration. Ideally you don't put references to any physical names in your configs. That way when you switch servers you can build your new server along side your old server and then when you want to switch to a new servers you just flip the CName over to the new server.
