renameCollection works from the shell:
> db.oldName.find();
{ "_id" : ObjectId("4df78a754a235ac761000000"), "name" : "user1" }
> db.oldName.renameCollection("newName");
{ "ok" : 1 }
> db.newName.find();
{ "_id" : ObjectId("4df78a754a235ac761000000"), "name" : "user1" }
I created a script "upgrade.js":
if(db["oldName"].findOne()) { db["oldName"].renameCollection("newName"); }
and running it creates an empty "newName" collection:
> db.oldName.findOne();
{ "_id" : ObjectId("4df78a754a235ac761000000"), "name" : "user1" }
> db.newName.findOne();
null
I can workaround this issue by inserting all the records from the old to the new collection and then dropping the old collection, but its not very clean.
