Upgrade the KV store server version

Splunk Enterprise versions 10.6 and higher do not use any previous KV store server versions. Instead, immediately after upgrading to Splunk Enterprise 10.6, your deployment is automatically upgraded to a new cohosted KV store. This upgrade is mandatory in Splunk Enterprise 10.6 and higher.

If you currently have Splunk Enterprise version 10.2 or 10.4, and a KV store server version 7.0 or higher, then your KV store is ready to for you to upgrade to Splunk Enterprise 10.6. You do not need to upgrade your KV server version any more.
