Symptoms

After Provider upgrade the UX1 Subscription Management microservice component to version 5.3.1603, a customer and/or a reseller wants to place an order for a partial upgrade of Microsoft NCE subscription with the seat transfer to a new subscription using the UX1 panel, but the option to Partial Upgrade is not showing in the UX1 subscription details within CCP.

The plan has the upgrade paths configured and an immediate switch allowed as per documentation here.

All the others requirements from this documentation page are meet as well, namely:

Note: If a subscription does not have the Active status, it has pending orders, or number of seats is equal to the value set in Min Units, the Partial upgrade button on the Subscription screen and the Partial upgrade wizard will be unavailable.

Cause

The cause of the issue is due to the fact that Partial Upgrade Flag should be synced not only on "Sync Price" option as per new software related issue with ID #OA-35278.

Resolution

The issue has been fixed in CBC 21.12.

Please consider upgrading to the latest version.
