You may have to set legacyCloud=true in your cluster properties. In the Solr reference guide (7.0) there's a section "Changes to Default Behaviors" that'll tell you a bit about that. Check your cluster properties (top level znode in ZooKeeper).
Or, try the MIGRATESTATEFORMAT collection API on your 6x collection first. If your current installation has a single clusterstate.json that contains all of your collection information, then this would be indicated. Mind you I'd experiment on a non-prod system first....
