Are you trying to merge them together somehow? You could write some
Lucene code to manage it directly with the raw indices but ES doesn't
support this.

And even if you did merge them together, you won't be able to get ES
to recognize the new index. Best to just reindex into a 0.19.8
cluster where you'll be able to back-up the files on disk and
revivify them later (that feature was added during that version).
