"Update" _id in mongodb document-CodePudding

PS: I only have to do this due to business requirements

I'm able to achieve it using mongosh, but since there are multiple records to be updated, I'm trying to implement a simple python script to automate the task.

Is it possible to do this with pymongodb?

// store the document in a variable
doc = db.clients.findOne({_id: ObjectId("4cc45467c55f4d2d2a000002")})

// set a new _id on the document
doc._id = ObjectId("4c8a331bda76c559ef000004")

// insert the document, using the new _id
db.clients.insert(doc)

// remove the document with the old _id
db.clients.remove({_id: ObjectId("4cc45467c55f4d2d2a000002")})

I'm not able to set the new Id in the doc variable in order to insert the new document that will mirror the old one.

Thanks

Here's a pymongo equivalent:

from pymongo import MongoClient
from bson import ObjectId

db = MongoClient()['mydatabase']

old_doc_id = '4cc45467c55f4d2d2a000002'
new_doc_id = '4c8a331bda76c559ef000004'

doc = db.clients.find_one({'_id': ObjectId(old_doc_id)})

if doc is not None:
    #  set a new _id on the document
    doc['_id'] = ObjectId(new_doc_id)

    # insert the document, using the new _id
    db.clients.insert_one(doc)

    # remove the document with the old _id
    db.clients.delete_one({'_id': ObjectId(old_doc_id)})
