Hi, we have a SolrCloud 6.3 with HDFS setup and plan to upgrade to 7.2.1.
The cluster upgrade instructions on https://lucene.apache.org/solr/guide/7_2/upgrading-a-solr-cluster.html does not contain any information on changing the luceneMatchVersion. If we change the luceneMatchVersion manually is it enough to just reload the collection or do we need to perform an index upgrade like the IndexUpgrader tool (https://lucene.apache.org/solr/guide/7_2/indexupgrader-tool.html) does? If so how would one use that for an index stored in HDFS?
regards, Hendrik
