Not really ... uptime is irrelevant because they aren't in production. I 
just don't want to spend the time reloading 1TB of documents.

Basically, I have a bunch of (previously known as ... ) shards on one 
machine (I'd like them to stay on one machine) that aren't associated 
with a SolrCloud. I query them using


My current loading logic doesn't matter but rest assured, there are no 
duplicate uniqueIds across each shard.

I want to bring them all into a cloud collection. Assume I have 3 


as above, I currently query them as:


I want to be able to address all three as if they were shards of a 
collection, something like.

  => shard1 (was core1)
  => shard2 (was core2)
  => shard3 (was core3)

I want to be able to load to collection1. search collection1 etc.

I've tried


.. but it doesn't actually recognize the existing cores.
