Introduction
As part of the Frankfurt release, a documented procedure for upgrade is provided below.
...
That being said, it is still possible to support a Green/Blue type of upgradedeployment, which will deploy new Frankfurt components (possibly on a new namespace) and then do a data migration.
Upgrade Strategy In a nutshell
The proposed strategy is :
...
2) Migrate existing VNFs into the new setup, this implies to at least onboard them through SDC, including LoopTemplatesDCAE blueprint
3) Distribute new artifacts to CLAMP/POLICY/CDS/DCAE
At this point Loop migration is possible, it is recommended to define a control loop migration strategy based on the CNF/PNF/VNF migration strategy, for instance :
- Instantiate CNF/PNF/VNFs on the new setup
- Create and Instantiate Loops on the new setup (the SDC distribution has created loop templates on CLAMP)
- Migrate traffic from old to new setup (smooth migration or load balance)
- Stop traffic on old setup
- Delete old setup loops and CNF/PNF/VNFs
