MongoDB/KVStore Migration Failure from 9.0.4 to 9.2.2

[donaldwayne1975]

Upgraded my HF and Deployment servers from 9.0.4 to 9.2.2.  These are Windows servers.  Then I received KVStore/MongoDB failure messages.  I've tried the KVStore migration steps.  I've tried removing the .lock files from the mongo folder.  I am trying to get the MongoDB updated/upgraded to the latest version so the KVStore will stop complaining.  Any help to clear this up would be greatly appreciated.

Seems your first install of Splunk contained MongoDB for KVStores.  Very early in the release of 9 was supposed to contain an out of band upgrade from mmap to wiredTiger.  The link above is how the DB upgrade was to be handled and may still work for you.  I would recommend reaching out to Splunk support if you have a contract with them for support while you process this now.
