Chapter 7. Known Issues
7.1. Overview
When upgrading your OpenShift Container Platform cluster, there are two primary data migrations that take place. The first occurs while still running the current version of OpenShift Container Platform, and the second happens after the upgrade completes.
If the pre-upgrade migration fails, the upgrade will be halted and the cluster administrator must resolve any data consistency problems before attempting the upgrade again. If the post-upgrade migration fails, the upgrade will complete and the cluster administrator should investigate the data migration issues as soon as possible. This document catalogs known data consistency problems and how to resolve them.
7.2. Duplicate Ports in Service definition
Service objects have more strict validation rules, one that does not allow duplicate Ports entries (considering Protocol and Port pair). (BZ#1563929)

error: 1 resources failed to migrate
To resolve this issue:
-
Log in to the CLI as a cluster administrator and inspect the
Serviceobjects listed in the error. -
Edit the
.spec.portsof the objects removing duplicate ports keeping in mind that pair.spec.ports[*].nameand.spec.ports[*].portmust be unique.
