It depends whether you use Solr 4.0 features whether there are changes to the results. Personally I've found them pretty (surprisingly) compatible from an API perspective.
One of the benefits of SolrCloud is that it can make multiple systems operate as if they were one, so I can't immediately think of any reasons why using SolrCloud would require a change to your indexing (assuming you are currently indexing to a single node). But really, the best way to find out is to try it.
