Answer: As of Now Firebase not allows to update documents ids)

Suggestion: You should use relational ids or random ids (relational ids means suppose you have seller favorite collection you can give documents ids to movie/food ids)

CodePudding user response：

There is no way to update the document ID of an existing document. If changing course names is a use-case you need to support, consider using Firestore's built-in ID generation when adding your documents (so add documents using the add() method).

If you stick to your current model, you'll have to:

1. Read the existing document.
2. Write the date under the new ID.
3. Delete the original document.

Given the type of operation, you'll probably want to use a transaction for that.
