rename deep field in mongodb
// Create something to test
db.test.insert({deep: {prop: 5}});
// Rename field
db.test.update({'deep.prop': {$exists: true}}, {$rename: {'deep.prop': 'deep.property'}}, {multi: true});
// Move to another object
// Note: leaves dangling `deep: {}`
db.test.update({'deep.property': {$exists: true}}, {$rename: {'deep.property': 'deeper.deep.property'}}, {multi: true});
