Moving cloud firestore collection

Question

I have a scenario in which I want to move my top level, in other words first, collection to the third level. Is the only way to go about this to use third party import-export software with manipulation to do this, or is there a firestore feature that I am missing? All help will be greatly appreciated.

TopLevel>Documents>ThirdLevel, where top level is the first collection in the db. Just to give a better picture of what I am trying to say.

Answer 1

Firestore has no ability to move collections or documents. Instead, you can copy documents. You'll have to write code to read the contents of a document, then write those contents to a document in a new location, then delete the original document.

I know it's an old question, but just in case someone else needs this. It's now possible using google's cloud shell. Details available in this link: https://firebase.google.com/docs/firestore/manage-data/export-import

You have two options to export specific collections, modify them, then import them, or export the whole bucket, then import it back. As I understood you can't mix the operations for example export all and import specific collections.

Note: I believe you'll be charged for the read and write of all documents exported and imported. And billing must be activated.
