Kv store migration before or after Splunk upgrade to 9.0.1

Hi all,

we are planing to update to version 9.0.1. and I was wondering if the kv store migration from mmap v1 to WiredTiger  obligatory is? The first sentence from the Splunk documentatiosn says "Splunk Enterprise versions 9.0 and higher require the WiredTiger storage engine and server version 4.2" but I was wondering if something will go wrong if we don't perform the kv store migration before the Splunk upgrade or if we don't perform the migration at all.

 

Thanks!

@richgalloway - thanks for the quick response. Is the migration obligatory though or optional?

I recommend switching to wiredTiger before upgrading to 9.0.  Depending on your architecture, however, the upgrade may switch you wiredTiger automatically.   See https://docs.splunk.com/Documentation/Splunk/9.0.1/Admin/MigrateKVstore
