Este examen requiere tener la OCP Java SE 7.

Ya no es como antes que podías actualizar desde cualquier versión OCP o SCJP.

[Ernesto]

Pedro, ¿donde viste esa información? No encuentro esa restricción en el sitio de Oracle

[Pedro]

A mí también me costó encontrarla,

http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=653&get_params=p_id:154

luego pincha en Upgrades

el último enlace pone

Upgrade to Java SE 8 OCP from Java SE 7 OCP

si pinchas en View Upgrade Path te sale

que tienes que tener

Oracle Certified Professional, Java SE 7 Programmer

y hacer el examen

Upgrade to Java SE 8 Programmer 1Z0-810

el 1Z0-810 todavía no existe, está en versión beta y por eso se llama 1Z1-810

Es una faena la verdad, yo tengo la 5 y me pensaba actualizar a esta...

[Dani]

Por lo que parece quien tenga la certificación de las versiones 5 ó 6 sí se puede actualizar a Java8.

Hay un par de hilos en JavaRanch que comentan el tema:
