Move to new website

Hi

We have used you Real3D FlipBook WordPress Plugin for a few years and it is great. We have purchased support a number of times and have hardly ever used it. Trying to sign up for additional support has been useless with envato as they do not respond.

My question is, we have a website that is built on a certain theme. It is old and we are building it on a new theme, so there will be a new WP database and Media Library. Can you tell me the easiest way to move the Real3D FlipBook WordPress Plugin and the bookshelf plugin and all their data to the new website and database. I can move the DB and tables from the old site and we realize the PDF’s and JPG covers would be located in different URLs in the WP Media Library. Also where is all the setup data located as we spent a lot of time getting it to work the way we needed. Any helpful info would be appreciated.
