Update from 1.3.4 to 1.4.0
You can update your existing CDP Private Cloud Data Services 1.3.4 to 1.4.0 without requiring an uninstall. After the update is complete, you can then upgrade the underlying OpenShift Container Platform from 4.5.x or 4.6.x to 4.7.x or 4.8.x.
If you are upgrading the OCP version, while the CDE service is enabled, it can cause database corruption in the embedded MySQL database used for CDE. Hence, only if you are using CDE Data Services, you must perform certain additional steps before starting the OCP version upgrade. Otherwise, you can directly update your CDP Private Cloud Data Services.
