Well – I am real sorry I went to bed and slept through the night and that my US colleague was stuck on an airplane until the early hours. But hey – I got up real early this morning so that I could answer you.
There are two main components to Simple:Press not including the actual plugin itself. The first, any physical files, are held in whatever you decided were the storage locations but by default are created in a folder called ‘sp-resources’ under the WordPress ‘wp-content’ folder. Mostly, when people move a WP website that will also move the entire ‘wp-content’ folder anyway.
The other component are the database tables and all Simple:Press tables start with the prefix ‘sf’ following your own WP prefix. E;g;., ‘sfgroups’, ‘sfforums’ etc.
So if you are moving the entire site as long as all the DB tables and the ‘wp-content;’ folder goes then mstly it should all be OK. A lot of people do this.
There are some notes in the codex FAQ here that also touch on any small changes you may nbeed to make after the move:
