MIGRATION SERVICES
Container Registry Migration and Transfer Services
Container Registry migration is a service that involves the seamless transfer of image repositories, tags, manifest configurations, access permissions, and live deployment processes to a new registry environment.
What is Container Registry Migration and Transfer Services?
A container registry migration is not just about copying image files from one repository to another. An improperly executed migration can lead to CI/CD process blockages in production environments, corruption of immutable image digests, and live deployment errors.
The process encompasses more than just image copying; it also includes the validation of multi-architecture manifest structures, robot account access, image storage policies, and CI/CD pipeline endpoints. Before closing the old registry environment, it must be proven that all active workloads can successfully pull and deploy images from the new source.
Service scope
Target Registry Preparation
Namespace, storage retention rules, access permissions, TLS certificates, and storage layers are configured.
Secure Image and Manifest Transfer
Images and manifest data are copied to the target environment in a consistent manner, ensuring integrity.
Consumer Systems Transition and Testing
CI/CD pipelines, deployment secrets, and Kubernetes/Docker definitions are redirected to the new registry endpoint.
WHO IS IT FOR?
Who is it for?
- Teams changing their container registry provider, domain, or infrastructure architecture.
- Organizations making transitions between cloud services such as GitLab Container Registry, Harbor, or AWS ECR / Azure ACR / Google GAR.
- Projects aiming to consolidate image repositories across different servers or environments into a centralized structure.
- Organizations reconfiguring their registry authentication and storage (retention) infrastructure due to security policies.

Frequently asked questions
Is it mandatory to transfer all historical image tags from the old registry?
Not necessarily. The scope of tags to be transferred can be clarified based on active versions, rollback requirements, and the organization's data retention policies.
Can image digest values change after the migration?
Digest values are preserved when images are directly copied without changing the manifest structure. However, images rebuilt from the same content during the migration may generate different digest values.
When is the old registry infrastructure completely shut down?
The old registry infrastructure is shut down when all CI/CD systems, Kubernetes clusters, and other consumers successfully pull and deploy images from the new source, and the specified acceptance period has been successfully completed without issues.
