Looking at the trial of Capture One and seeing it has an Aperture library import tool, trouble is my Aperture Library is an iPhoto Library so it doesn't want to import using the Capture One tool. Despite these being "the same" and openable by both iPhoto and Aperture there are clear differences in some package contents (no, renaming the library "Aperture Library" isn't enough to fool Capture One). What is my best bet here, in Aperture create a "native" Aperture Library and import the iPhoto Library into it? Then import the Aperture Library into Capture One using its inbuilt tool? I <think> that is the only way to potentially preserve most library attributes through to Capture One....which is the only advantage to an Export Originals from Aperture and an Import Images from Capture One...? (Library is circa 650GB, mix of jpeg (70%) and RAW (30%) by data, all RAW automatically processed on import, would estimate approx 40-50% of images have edits). Any other advice welcome, no time pressure as I'm happy to run Aperture until library handling resolved.
