Chapter 8. Deprecated features

This section describes the deprecated features introduced in Red Hat OpenShift Data foundation 4.22.

Metro DR (Disaster Recovery) functionality based on external OpenShift Data Foundation and Red Hat Ceph Storage architectures is deprecated as of this release (4.22) and will be removed in version 5.1. OpenShift Data Foundation 4.23 will be the final release to support this configuration.

Starting with version 5.1, future Metro DR capabilities will transition exclusively to a Provider-mode architecture within IBM Storage Fusion Data Foundation. OpenShift Data Foundation will no longer natively provide standalone Metro DR capabilities.

Impact and Migration Path:

  • Support Lifecycle: Existing customers utilizing this technology can safely remain on version 4.23, which will receive full support until its End of Life (EOL) at the end of 2029.
  • Next Steps: Customers planning future deployments or looking to upgrade beyond the 4.x lifecycle are encouraged to plan a migration to the new Provider-mode Metro DR architecture on IBM Storage Fusion Data Foundation.
