What are you asking here? Indeed, Lucene 8 (and therefore Solr) will
not open an index that has ever been touched by Lucene 6x or earlier.
You must re-index into 8x.
You cannot spoof this with, for instance, IndexUpgraderTool and go
from 6->7->8. You must reindex from your system-of-record.
This has been discussed several times on the mailing list, please
search the mail archives for a fuller discussion.
Best,

The first part of the error message is consistent with the error:
-> 6 (needs to be between 7 and 9).
Hope this helps
