Hello @Stennie_X ,
I have installed the 4.4 version on new server and did this mentioned below to dump and restore from old db to new db
ssh -fN -L 27018:localhost:27017 <remote_host>
mongodump --port 27018 --db <remote_db_name> --username <remote_db_username> --password <remote_db_password> --archive | mongorestore --username <destination_db_username> --password <destination_db_password> --archive
After running these commands on my new server I see my db when I do show dbs on mongo shell however when I change the port to 27018 in mongodb config file in order to run this restored db its throwing error and exiting with 42 saying address already in use and Its happening because of the ssh tunnel and when I kill the port and re run it now I dont see the restored DB .
Can anyone help me ?
