He actualizado con éxito una base de datos magento 1.4.1 a 1.4.2 y luego a 1.6.0. También pude migrar con éxito : configurar y migrar: datos de la base de datos 1.6.0 a mi base de datos Magento 2.1.2. (¡Las cosas se veían geniales! ...)
Desde entonces he estado trabajando en el sitio 2.1.2; agregar un nuevo tema, cambiar algunas configuraciones y editar bloques de cms. Hice todo esto con la suposición de que podría ejecutar una migración: delta y traer nuevos datos de clientes y pedidos, ya que eso es todo lo que realmente necesitaría para lanzar el nuevo sitio. (No he creado ningún nuevo pedido o cliente en la base de datos 2.1.2)
En mi intento de migrar: delta (después de ejecutar el proceso de actualización 1.4.1 -> 1.6.0 nuevamente para obtener los datos actuales en vivo) me topé con un error de perder las tablas deltalog (con el prefijo m2cl *). Saqué esas tablas, que estaban todas vacías , de la primera base de datos desde la que migré. Esto me permitió ejecutar una migración: delta con las siguientes advertencias:

Supongo que mi pregunta son algunas preguntas:
- Es el enfoque que tomé de manera correcta para obtener datos de 1.4.1 a 2.1.2
- ¿Hay alguna referencia faltante que está buscando migrate: delta
ya que esta base de datos actualizada no era la original desde la que migré? - y la pregunta del título.
