If you would like to migrate your data into MongoDB deployment, the following steps will help you clear the obstacles in the migration process.

Execute command

mongorestore -h <domain name> -d <database> -u <dbuser> -p <dbpassword> --authenticationDatabase "admin" --archive=<backup file path>

to import all data in the above backup file into MongoDB deployment. Take the following command as an example to import your data

mongorestore -h 172.107.32.103:27017 -d db1 -u root -p passwd --authenticationDatabase admin --archive=/data/mongodump-20180523.archive
