Scope

Support PNF software upgrade with schema update including service level LCM operations
- PNF software upgrade with updated service template
- PNF schema update with updated service template
- Service template update with multiple resource instances
Including:
- Updating the design time service template using vendor provided onboarding package
- Upgrading a run time service instance based on the updated service template
- Updating the run time catalog at software upgrade completion

Schema Update

Vendor delivers
- PNF box with pre-installed software, and
- PNF package which describes the functions supported by the PNF box
At PNF software upgrade, a new software version is running in the PNF box which may introduce new functions. Without schema updates, the ONAP is not aware of any of the new functions, e.g. new PM counters, new CM Yang model, new Alarms, etc.
In order to update the ONAP with the new functions introduced by the upgraded PNF software,
- a vendor shall provide a new PNF package with updated artifacts and the new PNF software image to the operator.
- the operator shall update the resource / service template based on the received PNF onboarding package, and upgrade the PNF software and update the run time catalog

Key Issues

Enable software version (Modelling/SDC/AAI):
- Onboarding the software version information using vendor provided onboarding package
- Supporting software version in internal model
Store the upgrade path info at design time (SDC/SO/VID):
- Resource upgrade path
- Service upgrade options
Run the upgrade at service level (SO): Executing the workflow at service level
Update the run time catalog (AAI):
- Support updating resource model ID/version
- Support updating service model ID/version
