Answer 1

If you are not using replication.

1 - You need to backup your database:

mongodump -d db_name YOUR_BACKUP_LOCATION

mongodump documentation

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

mongorestore documentation

Done.
