// Params:
// 1. query (filter) if you only want to remove this field from some records. {} will select any.
// 2. $unset the field(s) that you want to remove. Here I've set them to null but the value doesn't matter as it's ignored.
// 3. multi must be set to true otherwise it will only operate on the first record that it finds.
// 
// Run this command in the MongoDB shell

db.<collectionName>.update( {}, {$unset: {<fieldName1>: null, <fieldName2>: null}}, {multi: true});

guyellis

// Params
// 1. {} add a query in here if you don't want to select all records (unlikely)
// 2. $rename one or more fields by setting the keys of the object to the old field name and their values to the new field name.
// 3. Set multi to true to force it to operate on all documents otherwise it will only operate on the first document that matches the query.
//
// Run this in the MongoDB shell.
