What ate the two possible options to upgrade Common Services from the Extended Update Support...

IBM Cloud Pak for Integration (CP4I) v2021.2 relies on IBM Cloud Pak Foundational Services, which was previously known as IBM Common Services. Upgrading from the Extended Update Support (EUS) version (3.6.x) to a continuous delivery version (3.7.x or later) requires following IBM's recommended upgrade paths. The two valid options are:

Using IBM's provided script (Option D):

IBM provides a script specifically designed to upgrade Cloud Pak Foundational Services from an EUS version to a later continuous delivery (CD) version.

This script automates the necessary upgrade steps and ensures dependencies are properly handled.

IBM's official documentation includes the script download links and usage instructions.

Using the IBM Cloud Pak Foundational Services operator update button (Option E):

The IBM Cloud Pak Foundational Services operator in the OpenShift web console provides an update button that allows administrators to upgrade services.

This method is recommended by IBM for in-place upgrades, ensuring minimal disruption while moving from 3.6.x to a later version.

The upgrade process includes rolling updates to maintain high availability.

Option A (Click the Update button on the Details page of the common-services operand):

There is no direct update button at the operand level that facilitates the entire upgrade from EUS to CD versions.

The upgrade needs to be performed at the operator level, not just at the operand level.

Option B (Select the Update Common Services option from the Cloud Pak Administration Hub console):

The Cloud Pak Administration Hub does not provide a direct update option for Common Services.

Updates are handled via OpenShift or IBM’s provided scripts.

Option C (Use the OpenShift web console to change the operator channel from stable-v1 to v3):

Simply changing the operator channel does not automatically upgrade from an EUS version to a continuous delivery version.

IBM requires following specific upgrade steps, including running a script or using the update button in the operator.
