 ## Migraciones de datos
 
 Para poder migrar los datos desde la base de datos "antigua", previamente necesitamos poder tener un esquema de base de datos con un dump de OpenGnsys. Es decir:
+
     - Creamos una base de datos temporal simulando una insancia de OpenGnsys 1.1. La solicitaremos al equipo de desarrollo de las universidades
     - Necesitaremos un dump de la base de datos de OpenGnsys 1.1.
