Change input pdf of a form

[HetBruist]

Hi, I made a layout in InDesign and exported it to pdf. There I converted the pdf to a form with several fields. Now I need to make a few changes to the lay out. Is there a way to prevend that I need to remake all the fields? If I export the Indesign document it over writes the complete pdf.

Open the old document with the form fields. Then use replace pages with the pages of the new document.

InDesign is capabale of making interactive PDFs with form fields. So depeneding upon how complex your form fields are, you may just be able to do all your work in InDesign and export a new interactive PDF, and not worry about overwriting the old one. 

What kind of form fields did you make and where did you make them?
