I am assuming you want to get the borehole locations from each project in gINT with related attribute data? I've been a gINT user for over 20 years and the issue I see is and you've run into is there not being a way to batch export all the projects at the same time. There is a way to batch import your databases into one, I have never tried it and it looks like you have to have a project open, so maybe test it with an empty project https://communities.bentley.com/products/geotechnical1/f/geotechnical-forum/231504/how-to-combine-mu... The only other thing I can offer is taking a look at OpenGround, we have not switched to it yet, but maybe there is a way when transferring gINT projects to OpenGround you can merge data?
