OK, then what do you mean by: bq: I'm trying to upgrade a Solr 4.6 index to Solr 6. The upgrade does fail with an error.
?? Exactly what steps did you follow when you saw the failure? Because is sounds like you tried to put a Solr 6 directory over a 4x index, but then you say you're aware that you can't do that so I'm all confused. Did you try the 4.6 checkindex program?
