You don’t even have to copy the interactive elements over to the new file. Now, go to Acrobat Pro and open your old PDF containing the interactive elements that needs to be updated with this new content.
If you are using CS6 or newer, consider building your form in In Design so that when you export the PDF all fields are included, and you don’t have to edit them in Acrobat at all.
You can update your publications as often as you need.
