Renditions best practice. What's best in translating folio design to another platform?

Thanks Bob, but that wasn't quite my question. What's the best practice for workflow to convert the folio I've built into another size. EG Converting the iPhone articles to iPad. I was going to use the Page Tool, but wondered whether anyone had a more efficient method.

No worries, I worked it out. Save As the INDD document into the same folder under a different name, use Page tool to create the new dimension, create a new folio of the same name in the Folio Builder but different dimensions, and Add. Thanks anyway.

Thanks Bob. I thought I might be able to do it with Alternate Layouts, but realised they must be all the same aspect ratio - which clearly iPhone and iPad are not. I had hoped to be able to sync any changes within the document. Guess I better just get it right the first time!

Thanks Neil, that's what I thought originally. Can you direct me to any solid reference/instruction on using Alternate Layouts for renditions? I've been searching for days.

Brilliant, thanks Neil. That helps put me on track
