summary

Explains a concrete workflow for CRD versioning using kubebuilder scaffolding: a demo splits a single fullName into firstName/lastName, implements a conversion webhook that maps fields (storing dropped data in annotations for lossless rollback), and marks v1 as hub/stored then flips storage to v2. Shows hub‑and‑spoke conversion to cut N^2 converters down to hub conversions, observes clients prefer higher served versions, and verifies automatic migration via the storage version migrator (probes every 10 minutes, migration status succeeds).
