Answer 1

When you create a connection with mongodb then database is created automatically if not exist already.
You can use mongodump command to get all the database records and mongorestore to restore your database on your new machine.

Answer 2

Assumption: you have setup mongoDb locally and want to migrate it to another computer.
1.Requirements:
mongodump
mongorestore
1.1.How to install?
to install above requirement u have to install [MongoDB Database
Tools]
download link: https://www.mongodb.com/try/download/database-tools
1.2.Popular error.
sometime path is not set, so try this in cmd prompt: set path="C:\Program Files\MongoDB\Server\5.0\bin"
Note: please refactor the link according to your folder path.
2.Procedure:
Note: make sure you follow Step 1
2.1. Approach
we are going to create dump of mongodb from old pc(using mongodump), then transfer that dump to new pc, and import that dump using mongorestore.
2.2.Creation of dump in old pc(from where u want to replicate database)
cmd mongodump --host localhost:27017 --out ~/Desktop/mongo-migration
above cmd will create a dump in the mentioned path==> ~/Desktop/mongo-migration
just copy that folder and transfer it to new pc
Note: if you have created authenticated user then add these flag in above cmd and provide values --username [yourUserName] --password [yourPassword] --authenticationDatabase admin
2.3.Import of dump(created from old PC)
place that dump folder somewhere and execute below cmd
mongorestore C:/....../mongo-migration/ -u root --host 127.0.0.1:27017
done :)
