MongoDB has no built-in rename for databases — but mongodump and mongorestore get you there in two commands. Dump the old database to disk with mongodump -d old_db_name -o mongodump/, then restore it under the new name with mongorestore -d new_db_name mongodump/old_db_name. Verify the collections from the shell, drop the old database when you're satisfied, and you're done.
The full post walks through each step with the exact commands, plus the verification check that catches a half-restored copy before you drop the original.
