+-- =============================================================================
+-- Script spécialisé pour la migration des ir_attachment
+-- Gère les renommages de res_model et les modèles supprimés
+--
+-- À exécuter APRÈS la migration principale des données
+--
+-- IMPORTANT: Ce script doit être exécuté en 2 phases:
+--   1. Sur la BASE SOURCE (v13) AVANT export: Préparer les res_model
+--   2. Sur la BASE CIBLE (v19) APRÈS import: Valider et corriger
+--
+-- Modèles renommés v13→v19:
+--   mail.channel → discuss.channel (v16)
+--   payment.acquirer → payment.provider (v16)
+--   payment.icon → payment.method (v16)
+--   im_livechat.channel → discuss.channel (v16)
+--
+-- Modèles supprimés v13→v19:
+--   hr.expense.sheet → hr.expense (fusionné)
+--   account.invoice.send → NULL (wizard transient)
+--   account.bank.statement.import → NULL (wizard transient)
+--
+-- Modèles non installés (garder tel quel):
+--   fleet.vehicle, fleet.vehicle.model.brand, fleet.vehicle.log.services
+--   hr.contract (si module RH complet non installé)
