How to update the name of a Database in MongoDB?

Question

Aryan Kumar · Answer

You can update the name of a database in MongoDB using the renameDatabase() method. The syntax for the renameDatabase() method is as follows:

db.renameDatabase(oldName, newName)

Where oldName is the name of the database that you want to rename and newName is the new name of the database.

For example, the following code would rename the database mydb to newdb:

db.renameDatabase('mydb', 'newdb')

It is important to note that the renameDatabase() method does not move the data in the database. It simply changes the name of the database.

If you want to move the data in the database, you can use the copyDatabase() method. The syntax for the copyDatabase() method is as follows:

db.copyDatabase(oldName, newName)

Where oldName is the name of the database that you want to copy and newName is the new name of the database.

For example, the following code would copy the database mydb to newdb:

db.copyDatabase('mydb', 'newdb')

The copyDatabase() method will create a new database called newdb and copy all of the data from the database mydb to the new database.
