NFVI Upgrades and NFV Migrations with Live Critical Telco Workloads: Learnings and Challenges
summary
Two plus years of lab work runs NFVI upgrades with simulated traffic against an OpenStack plus Kubernetes stack and produces concrete lessons: upgrades are verified end to end with resilience tests, full data center upgrades can take months not nights, image backups and DB exports often take longer than redeploy so redeploy versus restore becomes a strategic choice, VM live migrations are straightforward but container drains need pod disruption budgets and kubeCTL dry-run, minimizing reboots and planning maintenance windows prove decisive for predictable in service upgrades.
