The import process has certain limitations. Some of them have workarounds.
- The Manager to Policy importer cannot roll back completely once the distributed firewall sections and rules are imported in phase 2.
Workaround: You must use the Backup and Restore feature in this case to restore the cluster to its original configuration in Manager.
- Clusters with load balancer CRD cannot be imported. Load balancer CRD have different spec in Manager and Policy mode and they cannot be transformed. Therefore, there must be no LB CRD present in the Kubernetes before initiating the import.
