db.collection.renameCollection(target, dropTarget)

Renames a collection. Provides a wrapper for the renameCollection database command.

dropTarget boolean Optional. If true, mongod drops the target of renameCollection prior to renaming the collection. The default value is false.


The db.collection.renameCollection() method operates within a collection by changing the metadata associated with a given collection.

Refer to the documentation renameCollection for additional warnings and messages.


The db.collection.renameCollection() method and renameCollection command will invalidate open cursors which interrupts queries that are currently returning data.

For Change Streams, the db.collection.renameCollection() method and renameCollection command create an invalidate Event for any existing Change Streams opened on the source or target collection.

Resource Locking

renameCollection() obtains an exclusive (W) lock on the database and blocks other operations on the database until it finishes.

Interaction with mongodump

A mongodump started with --oplog fails if a client issues db.collection.renameCollection() during the dump process. See mongodump --oplog for more information.


Call the db.collection.renameCollection() method on a collection object. For example:


This operation will rename the rrecord collection to record. If the target name (i.e. record) is the name of an existing collection, then the operation will fail.
