Thx for the advice Alan. I'm already aware of this fact (that's
why I used the checkIndex tool of Solr 5).

Solr/Lucene 6 can’t read 4.6 index files, only 5.x ones. So you’ll need to
upgrade from 4.6 to 5.x using the upgrade tool from the latest 5.x release,
then from 5.x to 6 using the current upgrade tool.
