- Support direct PNF NETCONF interface with the vendor-specific YANG model.
- Enhance SO in-place software upgrade workflow with generic SO building blocks, which can be used for workflow design in the design time.
- Using CDS self-service API between SO and controller with the support of PNF in-place software upgrade
- Enhance VID to demonstrate single PNF in-place software upgrade
- Enhance SO procedure to support AAI update after the software upgrade completion.
