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\', \         


        

Answer 1

I tried doing.

db.copyDatabase('DB_toBeRenamed','Db_newName','host') 

and came to know that it has been Deprecated by the mongo community although it created the backup or renamed DB.

WARNING: db.copyDatabase is deprecated. See http://dochub.mongodb.org/core/copydb-clone-deprecation
{
        "note" : "Support for the copydb command has been deprecated. See 
        http://dochub.mongodb.org/core/copydb-clone-deprecation",
        "ok" : 1
}

So not convinced with the above approach I had to take Dump of local using below command

mongodump --host --db DB_TobeRenamed --out E://FileName/

connected to Db.

use DB_TobeRenamed

then

db.dropDatabase()

then restored the DB with command.

mongorestore -host hostName -d Db_NewName E://FileName/
