I believe that separation of these forums is a very sensible step. I appreciate it.
The current version of the Associate certifcation in Java (OCA JP7) is quite different from its earlier version (OCA Java 5/6 or SCJA) in terms of its exam audience, pattern of questions, exam topics and the fact that OCA JP7 is a pre-requisite for OCP Java SE 7 certification. Due to these differences a lot of ranchers have been facing confusion while answering posts.
To make the separation clearer, I suggest creation of a sticky post in the old and new forums with a title, say, 'Who is this forum for?', which clearly states the exam title and exam number for the respective forums.
