You can split an index using the MultiPassIndexSplitter, which is in Lucene contrib. However, it won't use the same algorithm for assigning documents to shards, which means the indexes won't work with a SolrCloud setup.
A splitter that uses the same split technique but uses the shard assignment algorithm from SolrCloud could be a useful thing. But I have to say, I suspect it will be quicker/easier to just re-index. Make sure you choose the right number of shards, with SolrCloud as it is, you cannot change the number of shards without reindexing. This may change soon with newer releases of Solr though.
