+    # En supposant qu'une insertion prenne 10ms (ce qui est très optimiste),
+    # migrer tous les enregistrements de la db prendrait plus de 2h.
+    # C'est trop long.
+    # Mais d'un autre côté, j'ai pas assez confiance dans les capacités de nos
+    # machines pour charger presque un million d'objets en mémoire.
+    # Pour faire un compromis, les albums sont migrés individuellement un à un,
+    # mais tous les objets liés à ces albums
+    # (photos, groupes de vue, groupe d'édition, identification d'utilisateurs)
+    # sont migrés en tas.
+    #
+    # Ordre des opérations :
+    # 1. On migre les albums 1 à 1 (il y en a 1800, donc c'est relativement court)
+    # 2. On migre les photos par paquet de 2500 (soit ~une centaine d'opérations)
+    # 3. On migre tous les groupes de vue et tous les groupes d'édition des albums
+    #
+    # Au total, la migration devrait demander aux alentours de 2000 insertions,
+    # ce qui est un compromis acceptable entre une migration
+    # pas trop longue et une RAM pas trop surchargée.
+    #
+    # Pour ce qui est de la répartition des tables, quatre nouvelles tables
+    # sont créées : sas_album, sas_picture,
+    # sas_pictureviewgroups et sas_picture_editgroups.
+    # Tous les albums et toutes les photos qui sont dans core_sithfile
+    # vont être copiés dans ces tables.
+    # Comme les albums sont migrés un à un, ils recevront une nouvelle
+    # clef primaire.
+    # Pour les photos, en revanche, c'est beaucoup plus sûr de leur donner
+    # le même id que celui qu'il y avait dans core_sithfile.
+    #
+    # Les identifications des photos ne sont pas migrées pour l'instant.
+    # Ce qu'on va faire, c'est qu'on va changer la contrainte de clef étrangère
+    # sur la colonne des photos pour pointer vers sas_picture
+    # au lieu de core_sithfile.
+    # Cependant, pour que ça marche,
+    # il faut qu'au moment où ce changement est effectué,
+    # toutes les clefs primaires référencées existent à la fois dans
+    # les deux tables, sinon les contraintes d'intégrité ne sont pas respectées.
+    # La migration de ce fichier va donc s'occuper de créer les nouvelles tables
