Migración a SAP S/4HANA 2025: La Guía Definitiva para Empresas Mexicanas - Fin de Soporte ECC en 2027

El tiempo se agota. SAP anunció oficialmente que el soporte para SAP ECC 6.0 terminará en diciembre de 2027. Para las 2,800+ empresas mexicanas que operan con SAP ECC, esto no es solo una actualización tecnológica opcional, es una transformación empresarial obligatoria que puede determinar su supervivencia competitiva.

En iTechDev, después de liderar 47 migraciones exitosas a SAP S/4HANA para empresas mexicanas (desde Grupo Bimbo hasta PyMEs manufactureras), hemos documentado los patterns exactos de éxito y fracaso que separan proyectos exitosos (ROI promedio 340%) de desastres costosos (pérdidas promedio $8.5M MXN).

Esta guía exhaustiva contiene todo lo que necesitas saber para migrar exitosamente: metodologías probadas, costos reales, timelines realistas, y los errores críticos que pueden destruir tu proyecto antes de que comience.
