SUMMARY With Digikam 6.3, import pictures. Observation: some pictures already imported with previous version of digikam (e.g. 6.1 or older) are not recognized as already downloaded. Note: the opposite is also true: import pictures with Digikam 6.3. In Digikam 6.1, import pictures: observe that some pictures imported with 6.3 are not recognized as already downloaded. If I again import an already unrecognized imported picture, I see in the digikam4.db (DownloadHistory table) that the filedate is not the same for both imports. My guess: with Digikam 6.1 and older, EXIF date was used while with 6.3 filedate is used to store the date in db. As a result, loss of compatibility between 6.1 and 6.3. (I have not tested 6.2)
The date format has not changed between the digiKam versions. However, if you have used or did not use metadata in the camera settings, a different date may be created. We can not do anything about that. Maik

Hum, indeed, if I play with the setting "Use file metadata (makes connection slower)" in Settings > Camera > Behavior, I have no recognition problem anymore. Something has changed between 6.1 and 6.3 regarding this setting.
Thanks for the feedback. I close this file now. Gilles Caulier
