Read and compile multiple .gpj projects into a new database

Hello - we have a lot, let's say several hundred to thousands, of gINT project files located on several different network servers.  We'd like to compile all of our borehole x/y, some lithology, etc. to a web map for internal use. 

I'm realizing now that Professional Plus allows multi-project data storage in SQL, but we're just using Professional.  Does anyone have any suggestions as to a method or best practice to access (or export from gINT as a batch somehow) all of our existing gINT gpjs > grab info from the tables > and put into a new standalone database (SQL, PostGIS, etc.)?  I'm basically looking for batch/programmatic options to access each of the smaller .gpj and import into separate stand alone database, I apologize if this is apparent somewhere in the literature - and thanks in advance for any advice!
