    Description

      See last comments in SOLR-7844. The latter changed the structure of the leader path in ZK such that upgrading from pre-5.4 to 5.4 is impossible, unless all nodes are taken down. This issue adds a fallback logic to look for the leader properties on the old ZK node, as discussed.
