If you are not using replication.
1 - You need to backup your database:
mongodump -d db_name YOUR_BACKUP_LOCATION
2 - Stop MongoDB service
3 - Change configuration
storage:
dbPath: "YOUR_LOCATION"
engine: wiredTiger
Use new location. It will be easier to go back if something goes wrong.
4 - Start MongoDB service
5 - Restore database from backup
mongorestore YOUR_BACKUP_LOCATION
Done.

If my dbpath is "c:\data\db" and how I can tell that – Gopinath Navaneethan Mar 25 '16 at 11:16

First you simply connect with mongodump to your mongod instance (like with mongo) to backup database. your connection string will look more like this mongodump -d db_name -h localhost:27017 -u USERNAME -p PASSWORD -o c:\backup – Bonanza Mar 25 '16 at 11:22

It will be fine. Remember to create backup first! – Bonanza Mar 25 '16 at 11:25
