Adobe Experience Manager DAM (CQ5) has had the ability to generate thumbnail previews of InDesign documents since CQ5.5. It creates thumbnails by communicating with Adobe InDesign Server. Unfortunately the out of the box setup only produces a thumbnail of the first page, however this is easily tweaked to created previews of every page in the InDesign file.
Don’t forget to hit save, close the workflow and try importing a new InDesign Document to DAM. Assuming InDesign Server is set up correctly, you should now see additional page previews!
I’ve tested this out on CQ5.5, CQ5.6 and 5.6.1. If you get stuck, check out the video to see what you might have missed.
Big thanks to Sameer Charles for his work on this.
