Migration Guide#

This guide offers comprehensive, step-by-step instructions for migrating artifacts from Mirantis Secure Registry (MSR) versions 2.x and 3.x to MSR 4.x. It ensures a smooth transition, preserving data integrity and minimizing downtime throughout the migration process.

The transition to MSR 4.x introduces a fundamentally updated code base, enhancing performance, security, and scalability. Review whats-new to understand any changes in Mirantis Secure Registry behavior.

If you are using custom repository permissions, custom image signing, or Swarm, review removed-features and what-to-expect-when-transitioning carefully. If you have any questions, contact support for further guidance.
