Yeah, the link you referenced will work. It is _very important_ that you create your collection with exactly one shard then do the copy.
After that you can use SPLITSHARD to sub-divide it. This is a costly operation, but probably not as costly as re-indexing. That said, it might be easier to just create a new collection with shards and re-index, it depends of course on how painful reindexing is….
