Upgrading InDesign files from CC18 v13 to CC19 v14 and IDML
Our projects usually run a year and span may hundreds of ID files. We usually keep the project in the same version of ID throughout is life cyle. In the past when moving to different versions of ID we have our in-house staff and vendors export the files to IDML and then open in the newer version. We know this is necessary if someone happens to open and save in a newer version of ID accidentally.
We have a large project that because of workflow changes we are considering moving from v13 to v14. We also use a content management system with a InDesign/InCopy workflow. Is it absolutely necessary to IDML if upgrading one version higher. With the amount of files we're looking at, it does add considerable amount of time even with scripts. Though we have found it maybe cleaner as far as file integrity.
Thanks
