GCP Project Migration - Maintain IDs

Question

I'm migrating a project from no organization to a new organization. Will the project ID, dataset IDs, and any other IDs remain the same? Are there any potential disruptions besides those mentioned in this document ?

Answer 1

According to official documentacion, the project ID can only be modified when you're creating the project, after that you can not modify the project ID. So when you migrate your project to a new organization, the project ID will not change.

Regarding your question about the dataset's ID , once you create a dataset it can't be relocated, but you can make copies of a dataset, manually or using the BigQuery Data Transfer Service . When you copy your dataset to a new location, you can choose to create the new dataset with the same ID or use a different one.

To manually move a dataset from one location to another, follow this process:

Export the data from your BigQuery tables to a Cloud Storage bucket in either the same location as your dataset or in a location contained within your dataset's location. For example, if your dataset is in the EU multi-region location, you could export your data to the europe-west1 Belgium location, which is part of the EU.

Copy or move the data from your export Cloud Storage bucket to a new bucket you created in the destination location. For example, if you are moving your data from the US multi-region to the asia-northeast1 Tokyo region, you would transfer the data to a bucket you created in Tokyo. For information on transferring Cloud Storage objects, see Copying, renaming, and moving objects in the Cloud Storage documentation.

After you transfer the data to a Cloud Storage bucket in the new location, create a new BigQuery dataset (in the new location). Then, load your data from the Cloud Storage bucket into BigQuery.
