I have converted my CR2 library in Lightroom to DNG in Adobe converter. But then Lightroom do not recognize the DNG files as the earlier CR2 files. How do i get LR to sync the new DNG to the old CR2 file with all develop and rating i have done on the photos?? Is there a way to fix my problem?
Next time, convert to DNG from within Lightroom and this won't happen.
I don't know if it is possible to reconnect your edits. Do you have a backup of the CR2 files you could restore and then do the conversion in Lightroom?
Another possibility is this Plugin: Syncomatic - Sync files with same name or time it may be able to do what you are trying to do.
