Hi The template PDF has the exact same form fields (and also javascript code behind the form events) as the source PDF. So, I'd like to open the source PDF, get all filled out values (text, checkbox, pushbuttons, you name it) and put it into the template PDF and store it as a new output PDF.
Background: the template PDF has been created after the firm's organisational CI/CD change. It's not immediately clear what really has changed in the template PDF (some text, maybe a logo and the firm's name; hence my third approach of only altering the source PDFs to do a search and replace), however forms remained the same. Hope I explained myself a bit better.
