I'm trying to merge two documents by just moving the pages from one document to another. My spreads get screwed up when moving pages between documents. The last page of one document and first page of the second document are on separate spreads by themselves (that is, a spread with only one page). I can't seem to put them on one spread. The first page of the second document does start over with page 1 (where my page numbering starts; the first document is the front matter of the book.) Would appreciate any advice. Thanks.
Have you tried playing around with the "Allow pages to shuffle" and "Allow spreads to shuffle" settings in the pages palette? Try toggling them for the relevant spreads and then dragging them into the right place. I did a quick test, and if your spread page numbers have square brackets around them they are quite ornery and do their own thing, but without the brackets they slot in where you want them.
