How do you rename a MongoDB database?

Question

There's a typo in my MongoDB database name and I'm looking to rename the database.

I can copy and delete like so...

db.copyDatabase('old_name', 'new_name'); use old_name db.dropDatabase(); 

Is there a command to rename a database?

Answer 1

You could do this:

db.copyDatabase("db_to_rename","db_renamed","localhost") use db_to_rename db.dropDatabase(); 

Editorial Note: this is the same approach used in the question itself but has proven useful to others regardless.

Answer 2

Alternative solution: you can dump your db and restore that in different name. As I've experienced it's much quicker than db.copyDatabase().

$ mongodump -d old_db_name -o mongodump/ $ mongorestore -d new_db_name mongodump/old_db_name

This is the current official recommended approach for database renames, given that copyDatabase was removed in MongoDB 4.2:

The "copydb" command is deprecated, please use these two commands instead:

1. mongodump (to back up data)
2. mongorestore (to recover data from mongodump into a new namespace)
