I'm trying to migrate kvstore on a v8.2 installation on Windows, but it fails early in the process. splunk migrate kvstore-storage-engine --target-engine wiredTiger ERROR: Cannot get the size of the KVStore folder at=E:\Splunk\Indexes\kvstore\mongo, due to reason=3 errors occurred. Description for first 3: [{operation:"failed to stat file", error:"Access is denied.", file:"E:\Splunk\Indexes\kvstore\mongo"}, {operation:"failed to stat file", error:"Access is denied.", file:"E:\Splunk\Indexes\kvstore\mongo"}, {operation:"failed to stat file", error:"Access is denied.", file:"E:\Splunk\Indexes\kvstore\mongo"}] I've tried to do file operations on the folder and subfolders of E:\spunk\indexes\kvstore\mongo and everything seems ok. The mongod.log does not contain any rows from the migration. Any nudges in the right direction? Can I upgrade to 9.1 without migrating the store?
