The short answer is I don't know. The option of going 10g OCA to 11g OCP is not listed on the website.http://education.oracle.com/pls/web_pro ... d:Datab11g
The SQL exam you took is still valid, so it looks like you have two choices:
1) Do the two 11g Admin exams, do the hands-on course and get OCP 11g.
2) Do the second 10g Admin exam, do the hands on course and get OCP 10g. Then take the 11g upgrade exam.
Either way it is two exams and a course. One what makes you OCP 11g, the other makes you OCP 10g and 11g.
You should check with Oracle education to see if there are some special circumstances that will let you go straight from 10g OCA to 11g OCP. it may be possible, just not listed?
