It is fairly straightforward to replace all the headers/footers regardless with the same header footer, by removing the existing header footer contents and writing a new header footer to the header footer ranges. The problem is that there are up to three header footer ranges for each section of the document. Which header/footers do you want to change.

Even more pertinent, why do you want you change the header/footers of all the old documents? New documents I can understand, but old documents would then no longer reflect the content at the time the document was produced. This can be important for letters and especially documents of a legal nature.
