We recently updated our designers to Indesign Cloud. However, editorial has Incopy CS6. I know the quick answer is to upgrade editorial. However, is there any way editorial can open Indesign cloud with their existing Incopy CS6 (maybe a plugin). We don't really want to upgrade if there's a solution to this as editorial just started using Incopy CS6 for few months. Editorial was using Incopy CS4 for a long time.
