Problems in switching over to responsive

I have my site created with the old Directory Press, with WP 3.5.2

Now, to make that mobile friendly, I purchased the responsive theme add on hoping that against installing that, it would go mobile smoothly.

After installing that on an other site I found there is nothing like “Article Manager” at all on that. It is a big problem for me & I don’t know how I solve that.

I have my major content created with articles. I do not have anything under listings etc. In a way, you can say I may not be using the “Directory” part at all at the moment. But I have many articles created under article manager & many of them on Google 1 position.

My point is :- How can I & what do I need to do to Switch over WITHOUT disturbing my link structure for indexing on google ?

I am desparately looking for the solution, otherwise this responsive thing is completely useless for me.

Alternatively I have also created 1 more post on this forum asking whether an upgrade to latest WP is feasible or not. So I shall create separate mobile site.
