Steps for migrating datastore and cloudstorage entities to another project

[Rob Curtis]

Hi,

I'd like to migrate existing data from one project to another.

If found this detail here which outlines the steps to https://cloud.google.com/datastore/docs/export-import-entities (however this is to firestore in datastore mode, is that the standard now?)

The issue I have is that the Google cloud storage records I have are accessed via blob_keys in a lot of cases and unfortunately we didn't store the filenames :(

So when migrating, do the blob_keys still work (provided I don't delete the GCS file associated with the blob_key on the old project?)

Are there any other gotchas to consider?

Thanks

Hi Rob,

Firestore is considered the newest version of Cloud Datastore, there are multiple benefits that come with this update.

After doing a little bit of research on this I've found a very interesting article that describes multiple ways to migrate blobs to a GCS bucket in another project. I personally think that in your case the option #2 which consist of using the open source tools[4] that would store a Datastore mapping from the existing blob key to the GCS filename and then running a simple gsutils cp[4] command seems to be the easiest option.
