If you're running SolrCloud, I would not try it. SolrCloud is evolving very quickly and so many things have changed that running mismatched versions is likely to break. I have tried CloudSolrServer from 4.6.0 against a SolrCloud running 4.2.1, and a simple query will not work because of changes in the data contained in zookeeper. If you're not using CloudSolrServer, it should work very well even with a wide version discrepancy. Switching to XML is not required. The javabin version has only changed once, in version 3.1.0. It has been stable since that time. Thanks, Shawn
