#
# migrate-luxnetwork-crds.sh — Phase A: lux.network/v1alpha1 → lux.cloud/v1
#
# Migrates all live CRs from the legacy `lux.network` API group at v1alpha1
# to the canonical `lux.cloud` API group at v1 (operator v0.6.3).
#
# Kind mapping:
#   LuxNetwork  → LuxNetwork  (name unchanged)
#   LuxChain    → Chain       (drop Lux prefix)
#   LuxGateway  → Gateway     (drop Lux prefix)
#   LuxIndexer  → Indexer     (drop Lux prefix)
#   LuxExplorer → Explorer    (drop Lux prefix)
#   LuxMPC      → MPC         (drop Lux prefix)
#
# Spec/status pass through opaque (both CRDs use
# x-kubernetes-preserve-unknown-fields: true).
#
# Mode of operation:
#   1. List source kind in source group
#   2. For each item: read full yaml, swap apiVersion + kind,
#      strip server-side metadata (resourceVersion, uid, generation,
#      managedFields, creationTimestamp, status), apply under new group
#   3. Verify both CRs coexist (legacy + migrated) before any deletion
#
# Idempotent: re-applying produces same target CR (server-side merge by name).
#
# Usage:
#   ./migrate-luxnetwork-crds.sh <kubectl-context> [--dry-run]
#
# Env:
#   YQ — yq v4 binary path (default: yq). Required.
