Eso implica avanzar por etapas: optimizar procesos online y batch, actualizar a COBOL 6, optimizar las conexiones <em>host to host<\/em>, exponer funciones mediante APIs para desacoplar los canales y, con el patr\u00f3n strangler, ir reemplazando componentes sin apagar el resto.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Cada paso se acompa\u00f1a con pruebas continuas y con planes para volver atr\u00e1s si algo falla.
