Since you still have your LR5 catalog you could move the current LR CC catalog to a subfolder and try converting the LR5 catalog again. This should not happen during the conversion process!
Thanks for the quick feedback. Yesterday I moved the LR CC to a subfolder and tried opening the LR5 catalog in LRCC to prompt a new conversion process. Somewhere during the process I received an error:
"Lightroom encountered problems when trying to update the format of the catalog file and cannot use this catalog in this version of Lightroom." See Adobe TechNote: https://helpx.adobe.com/lightroom/kb/catalog-corruption-error-photoshop-lightroom.html.
I then tried to open the LR5 catalog in LR5, and it seems to be working just fine.
I just tried to convert the LR5 Catalog again, and got the same error.
What do I try next?
Option 1) Close all applications and restart your system. Move the subfolder with the LR CC converted catalog file and Previews folder to your desktop or any other folder outside of the Lightroom folder. The Lightroom folder should then only contain the Lightroom 5 catalog file and Lightroom 5 Catalog Previews folder. Launch LR CC and try the LR 5 catalog conversion again. When it prompts you concerning the catalog choose the option to manually select a catalog. Navigate to the folder with your LR 5 catalog and Previews folder. It should then detect that it needs conversion and repeat the process.
Option 2) If that doesn't work I suggest trying the same procedure using your most recent LR 5 Catalog Backup file. Move the current LR 5 Catalog file AND Previews folder to a separate subfolder outside of the Lightroom folder. Copy over the LR 5 backup catalog file and relaunch LR 5 (not CC). This will cause LR 5 to create a new Previews folder. Confirm the new Lightroom 5 Catalog Previews folder has been created using Finder or Windows Explorer. Close LR 5 and relaunch LR CC.
Great news. Option 1 worked!
Good to hear. I suggest leaving LR5 installed until you are 100% certain everything is functioning properly in LR CC. Make sure you are backing up both your LR5 and LRCC catalogs to an external drive as well as your image files. Keep the current LR5 catalog on the backup drive as a safety measure.
well its seems i have the same problems but no matter what I do I seem to have lost all adjustments made to the DNG files, I have tried all of the above and nothing works. I don't know how these companies get away with it, surely an upgrade should mean "something better", it seems I have lost all adjustments. Will be ditching Adobe as soon as my subscription runs out.
I dont even have the changes showing that I made in LR5 anymore........................
After installing LR CC were you prompted that you're previous version catalog needs to be converted for use in LR CC? Did you allow it to complete the conversion?
Did you instead Import the DNG files into LR CC and have this setting checked in your previous version of LR?
Your previous version LR Catalog should still be in the same folder location and can be converted following my instructions here: https://forums.adobe.com/message/7530871#7530871
