Which is better, a mongodump or a mongorestore?
However, I realized today that doing a full mongodump followed by a mongorestore is a bit wasteful (I think) since I do all of the data transfer, then do all of the insertions. I would prefer to transfer data from the old mongo (the mongodump step) while simultaneously inserting available data into the new database (the mongorestore step).
How to run mongorestore from the command line?
Run mongorestore from the system command line, not the mongo shell. For example, to restore from a dump directory to a local mongod instance running on port 27017: Created with Sketch.

Which is the latest version of MongoDB dump?
For example, if your dump was created from a MongoDB Server running version 4.4.x, be sure that the MongoDB Server you are restoring to is also running version 4.4.x.

When to use mongoestore to load MongoDB files?
When using mongorestore to load data files created by mongodump, be sure that you are restoring to the same major version of the MongoDB Server that the files were created from. For example, if your dump was created from a MongoDB Server running version 4.4.x, be sure that the MongoDB Server you are restoring to is also running version 4.4.x.
How is mongodump used in a cron job?
