To take advantage of the improved concurrency in Mongodb 2.2--namely database level locking--we would like to move a sharded collection to a new database.
I have been unable to find any documentation which will help with this particular scenario.
I know I cant just "rename" this sharded collection: https://groups.google.com/d/topic/mongodb-user/lajAcp3HkZ4/discussion
The only thing I can think of is mongodump the entire collection and mongorestore into a new database. What are my other options?
