I made a template for my boss to insert text and images for each of his presentations. Unfortunately, I found that he absolutely hates InDesign and refuses to use it. I've never made something on Illustrator to be easily editable by multiple people, and I've also never exported from ID to AI. Would appreciate any tips and help! The files are very design-heavy, so it's not just simple text and white backgrounds.
There is no easy path from ID to AI. You can try copy/paste, but don't expect miracles. Export to PDF/X-4 might work, too, but you'll have a lot of cleanup to do in Illustrator (which is not a general purpose PDF editor).
