Storage migration
Automating the Move from gp2 to gp3
An automated Kubernetes storage migration completed with minimal downtime and zero data loss.
Professional case study
All in-use gp2 storage migrated
Zero data loss
Minimal downtime
Problem
All in-use gp2 EBS-backed Kubernetes storage needed to move to gp3 while preserving application data and minimizing downtime.
Action
Automated the migration with scripted workload scale-down, persistent-volume recreation, and recovery flows. Subsequently prevented new workloads from using gp2.
Outcome
Completed migration of all in-use gp2 storage to gp3 with minimal downtime and zero data loss, then enforced the new storage choice for future workloads.
engineering takeaways
Reusable patterns from the work.
These notes focus on the engineering judgment, tradeoffs, and patterns behind the work.
- Included workload scale-down and volume recreation in the migration workflow.
- Built recovery flows into the automation.
- Prevented new gp2 usage after completing the migration.
