Subject Re: Migrating from Solr 6.X to Solr 7.X: "non legacy mode coreNodeName missing"
Date Mon, 30 Oct 2017 15:55:51 GMT
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....

Best,
Erick
