Hi Wolfgang, I would say that your safest bet is to start from 7.5 schema, adjust it to suite your needs and reindex (better than to try adjust your existing schema to 7.5). If all your fields are stored in current collection, you might be able to use DIH to reindex: http://www.od-bits.com/2018/07/reindexing-solr-core.html <http://www.od-bits.com/2018/07/reindexing-solr-core.html>
I’ve recently used this approach for 4.x to 6.x.
