Migrate S3 object storage without service disruption

A clear path forward for teams running MinIO

Move forward safely without disrupting existing S3 workloads.

CLYSO's MinIO Migration helps organizations adapt their storage strategy while keeping production systems stable.

Organizations built their storage around MinIO for its simple, open S3 approach.

As the technology landscape changes, many teams are re-evaluating how they operate and plan their storage long term.

Understanding the current situation

The open-source era of MinIO has officially ended. The transition to a closed-source model (AIStor) creates immediate security and operational risks for community users.

The state of MinIO

  • Archived & Closed: The public repository is read-only. Development has moved to the proprietary AIStor.
  • No Distribution: Official Docker images and pre-compiled binaries have been discontinued.

    • The Risk for Operators

  • Security Gap: No more CVE patches or dependency updates from the original authors.
  • Total Liability: The user is now 100% responsible for security, patching, and compliance.

    • CLYSO MinIO Migration

    The MinIO Migration is CLYSO’s strategic response to the changing MinIO ecosystem. We help organizations move their S3 workloads to a stable, long-term foundation without risking their current operations.

    How we support you

    The goal is simple: Keep your systems running today while building a secure path for tomorrow.

  • Ending operational uncertainty around unmaintained builds.
  • Stabilizing existing environments during the transition.
  • Migrating safely to a sustainable S3 architecture (like Rook/Ceph).
  • Avoiding risky "big bang" cutovers that cause downtime.

    • Technical Background

    MinIO Migration by CLYSO is powered by Chorus, CLYSO’s S3 orchestration layer.

    Chorus sits between applications and storage systems and enables:

  • continuous data replication
  • parallel operation of source and target storage
  • controlled traffic routing
  • gradual transitions instead of disruptive cutovers

    • A typical project follows a clear process

    Applications continue using the same S3 API throughout the migration.

    1. Connect source and target S3 environments

    2. Start background replication

    3. Synchronize ongoing changes

    4. Validate data and performance

    5. Switch traffic in a controlled way

    Who MinExit is for

  • Production Teams: Companies running MinIO on Bare Metal or Kubernetes.
  • K8s Operators: Teams planning a move to Rook/Ceph for native orchestration.
  • Security-Conscious Orgs: Anyone requiring guaranteed CVE patches and updates.
  • Reliability First: Teams needing a safe migration path without service disruption.
  • Open Source Advocates: Organizations moving away from archived or closed-source models.

    • What you gain

  • Exit the Maintenance Trap: No more building and patching archived code yourself.
  • Full Compliance: A storage stack with active security monitoring and support.
  • App Continuity: Your applications stay compatible; no reconfiguration needed.
  • Low-Risk Transition: Move data at your own pace—no "big bang" required.
  • Strategic Peace of Mind: Trade technical debt for a professionally supported OS stack.

    • Real-world scenarios we support

    Most teams turn to CLYSO's MinIO Migration to find a structured, safe path for migrating their S3 storage to Ceph. Whether you are moving to a standard Ceph cluster or using Rook for Kubernetes orchestration, we ensure your transition happens without the risks of a manual cutover.

    Typically, our clients start from one of these situations

    The Kubernetes Shift

    Replacing MinIO in K8s clusters with Rook/Ceph to ensure long-term support and native cloud orchestration.

    Legacy Production Risk

    Operating multi-node MinIO setups that no longer receive security patches (CVEs) or updates from the original authors.

    The "Greenfield" Opportunity

    Planning new S3 environments (e.g., for NVMe storage or Veeam backups) while phasing out unmaintained legacy nodes.

    Scaling Challenges

    Managing millions of objects where traditional migration methods would cause unacceptable downtime or data risks.

    The Strategic Exit

    Moving away from a proprietary "AIStor" path back to a transparent, community-driven Open Source strategy.

    Frequently Asked Questions

    These are the questions we hear most often about CLYSO MinIO Migration.

    Features

    What is MinIO Migration by CLYSO?

    MinIO Migration is a migration and transition approach developed by CLYSO.

    It helps organizations move from changing MinIO environments toward a stable, long-term S3 storage strategy — without downtime.

    Why was CLYSO MinIO Migration created?

    Changes in how MinIO is distributed and maintained led many organizations to reassess their storage setup.

    MinIO Migration provides a structured and safe way to move forward while keeping applications running.

    Is the MinIO Migration by CLYSO a replacement for MinIO?

    No. MinIO Migration is not a storage product. It is a migration and orchestration approach that allows teams to move safely between S3-compatible environments.

    Do applications need to be changed?

    In most cases, no. Applications continue using the same S3 API while migration happens in the background.

    Is downtime required?

    No. The MinIO Migration is designed for controlled migration with continuous replication and planned traffic switching.

    Can we migrate gradually?

    Yes. Workloads or buckets can be migrated step by step instead of all at once.

    Is the MinIO Migraton suitable for enterprise environments?

    Yes. It is designed for production environments where stability, predictability and controlled changes are essential.

    Is the upstream MinIO repository still maintained?

    The official repository indicates it is no longer maintained and is archived/read-only; teams relying on it should plan accordingly.
