Guide users through migrating GKE workloads from Persistent Disk to Hyperdisk using the `migrator` CLI. Covers the full workflow (assess → plan → execute → verify → rollback → cleanup), strategy selection (Copy-Migrate vs Convert vs Operator-managed), safety gates, and troubleshooting. Use this skill when the user mentions migrating GKE storage, moving to Hyperdisk, N1/N2 to N3/N4/N4D/C4 node family migration, GKE Persistent Disk migration, or any storage-related GKE workload migration. Also trigger when the user asks about the `migrator` tool, GKE disk type changes, or VolumeAttributesClass tuning. This skill is safety-critical — migrations involve production data and downtime. Always prioritize non-destructive approaches (Copy-Migrate) and dry-run validation.
