Ofcource I did it. I did all changes in solrconfig.xml and used IndexUpgrader
from 4 to 5 and then from 5 to 6.

Klin,
You need to use the new version's solrconfig.xml, with modifications as
necessary. Start by looking at the current solrconfig, what was modified there?
Did you re-index? If you cannot reindex then you should upgrade to 5.n then to
6.m.

Before two days we upgraded our SOLR servers from 4.10.1 version to 6.5.1. We
explored logs and saw too many errors like:
1)
org.apache.solr.common.SolrException; null:java.lang.NullPointerException
at
org.apache.solr.search.grouping.distributed.responseprocessor.StoredFieldsShardResponseProcess
