Can’t log in after upgrading to 6.4.3edit


  • Native realm credentials don’t work after $version upgrade or snapshot restore.
  • Error message: "Security index is not on the current version - the native realm will not be operational until the upgrade API is run on the security index"


You must upgrade the .security index to the 6.x format. For instructions, see Upgrading internal indices.

There are two situations where it’s necessary to manually upgrade the .security index:

  • After upgrading directly to 6.4.3 from 5.5 or earlier.
  • After restoring a snapshot from 5.5 or earlier that contains a .security index in the old format to a 6.0 cluster.
