Is there any way to export an entire book (indb) file and import it in version CS6?
The only way we found is to export each document as IDML, which should in theory allow us to open it in CC. But that doesn't help us for the book. Maybe there's a plugin or something?
Also, exporting as IDML doesn't work for the document we need it for, it gets stuck at 65 %. I tried opening an older version (that opens in CS6) and exporting it from CS6, but that doesn't work either.
So is there another way to move the file to CS6 while keeping the format and layout intact?
There is no interchange format for .indb files, nor would it help since the .indb would continue to point to the original .indd component files. You must export each .indd to .idml, then open those in the earlier version and save as new .indd files and add to a new .indb Book file. You can use Peter Kahrel's batch conversion tool to make the .idml files: Free script Batch convert/export InDesign documents | Peter Kahrel
