Introduction

Renaming a database should be used with extreme caution. Be sure to backup the database first and confirm the new database before removing the old database.

Requirements

• MongoDB 2.6

Rename with Database Copy

Connect to MongoDB using the mongo shell.

mongo

The old database content can then be copied to a new database.

db.copyDatabase('old_database', 'new_database')

It is recommended that you verify the copy was successful before removing the old database. Once done, the old database can be removed.

use old_database
db.dropDatabase()

Rename with Backup/Restore

The mongodump and mongorestore commands can be used to backup the existing database and then restored into a database with the new name.

mongodump old_database
mongorestore --db new_database ./dump/old_database

The old database can be removed once a successful copy has been confirmed. Connect to MongoDB using the mongo shell.

mongo

The old database can then be removed.

use old_database
db.dropDatabase()
