As long as you're not accessing a SolrCloud cluster with CloudSolrClient, that should work well. HttpSolrClient tends to work well across a fairly wide version discrepancy -- the HTTP API changes infrequently and maintains backward compatibility very well. With the cloud client, such a large a version gap is more likely to run into problems, because SolrCloud changes very quickly from release to release, and the cloud client is *tightly* integrated with how the server functions.
