I suppose that the closure of this issue without any response means that the solution is to figure out how to revert back to HDB?
It was marked as a duplicate of an existing issue since that's what it is. See that ITS for further details.
That issue does not detail the same error, and none of my questions were addressed in it.
That's because it was hit via different paths. In the case I filed, it was using slapadd when slapd is offline. In your case, it was via a modrdn operation on a live server. The underlying problem is the same however.
