             Summary: SolrCloud upgrade path
                 Key: SOLR-4312
                 URL: https://issues.apache.org/jira/browse/SOLR-4312
             Project: Solr
          Issue Type: Task
          Components: SolrCloud
    Affects Versions: 4.0, 4.1
            Reporter: Steve Rowe


Upgrading from one SolrCloud version to another needs to be figured out and documented.

One issue that is probably still a problem is that you can't easily upgrade form a 4.0 to 4.1 SolrCloud setup in some cases - at least to my knowledge. I don't know all the details, but at a minimum, we should probably add an entry to changes about what you should do. It may require blowing away your own clusterstate.json and re doing your numShards settings, or starting over, or…I don't really know. I don't think anyone has tested.
