The Google Cloud Private Catalog recently released a new version enabling additional functionality which includes:
- Updated user experience
- Separate of products and catalogs to enable bulk actions and easy management of your resources
- Visibility into Catalog sharing and ability to unshare catalogs
- Terraform support

In order to use the latest release (Private Catalog 1.1), a migration will need to happen with your existing products and catalogs.  The migration will move your existing products to a common Google Cloud Project and will take a few minutes.

Attention: Manager role needs to be set at either the org level or on the target project.

This form will collect the required information and the migration will happen on the backend for you.  You will be notified by someone at Google once the migration is complete.
