Chapter 3. Updating Red Hat OpenShift Data Foundation 4.13 to 4.14
This chapter helps you to upgrade between the minor releases for all Red Hat OpenShift Data Foundation deployments (Internal, Internal-Attached and External). The upgrade process remains the same for all deployments. The Only difference is what gets upgraded and what’s not.
- For Internal and Internal-attached deployments, upgrading OpenShift Data Foundation upgrades all OpenShift Data Foundation services including the backend Red Hat Ceph Storage (RHCS) cluster.
For External mode deployments, upgrading OpenShift Data Foundation only upgrades the OpenShift Data Foundation service while the backend Ceph storage cluster remains untouched and needs to be upgraded separately.
We recommend upgrading RHCS along with OpenShift Data Foundation in order to get new feature support, security fixes, and other bug fixes. Since we do not have a strong dependency on RHCS upgrade, you can upgrade the OpenShift Data Foundation operator first followed by RHCS upgrade or vice-versa. See solution to know more about RHCS releases.
Upgrading to 4.14 directly from any version older than 4.13 is unsupported.
Prerequisites
- Ensure that the OpenShift Container Platform cluster has been updated to the latest stable release of version 4.14.X, see Updating Clusters.
Ensure that the OpenShift Data Foundation cluster is healthy and data is resilient.
