John. R. Ellis have mentioned suggested some corrective measure. Let me know if this solves your issue.
- I understand that the original catalog is still there and I also have backup copies. I have no way i've found yet to step back to the previous version on lightroom. I did not uncheck the 'delete old version' checkbox, so it is gone.
- I have looked more thoroughly and my original assessment is true. When I look at photos from 1967 to 2015, they are all fine up to January 1-7, 2015. All color labels and keywords present. The next photo was taken on January 22, 2015 and, from that photo to Today, all labels and keywords are missing.
- I tried reading metadata from a file and nothing happens (thinking data may be in a sidecar file).
- Akshay, I do not know what you are referring to when you say John R. Ellis corrective measures. I see no reply from this person. Only you and Carlos.
Guidelines for catalog upgrade :
1. Copy your Lr6 catalog file (only the lrcat file) to an internal drive, where available space is more than twice the size of your catalog. if(your catalog is 10 GB, I recommend you to have available disk space upto 25 GB) .
2. Clear any temp files in the directory where the lrcat file is present.
3. Check if your catalog opens in previous version of Lightroom (6.12)
4. If it does then try optimizing it , File -> Optimize catalog.
5. After optimizing. close all applications. Clear any temp files further created in the directory.
6. Disconnect any external drives connected.
7. Try upgrading your catalog with new LR Classic CC.
If you still face issues, please share your catalog with us. (Zip it, upload it to dropbox, share the link over private message), we will try to debug your problem asap.
So, what I did was select a 'folder' in the catalog, then CTRL-A, metadata > read metadata from file. I catalog my photos sessions by date (each folder is Year, subfolders for each day with photos) so, I needed to go to each folder (date) (30-60 in each catalog) then each subfolder (15-20 in each folder) and 'Select All' > Metadata > Read Metadata from File. FYI - If I used 'Update DNG Preview and Metadata', it was the same as 'Overwrite', so could not use this.
Needless to say, since I just discovered this, I am still going thru the first catalog (of many) trying to get all of my Metadata back! It saddens me, being a photoshop/Lightroom user since versions 1, to see Adobe begin to act like so many other software developers and push products, upgrades, etc out way too fast. Some I have seen lately, from other companies, are no better than Late Alpha, Early Beta releases. and are being sent out into the wild.
First I should explain my workflow to make the observations easier to follow:
After a day of shooting, here is what happens:
- Navigate to the main folder for the current year (F:\Year2017)
- Create a sub-folder using the date of the shoot as name (F:\Year2017\October 31, 2017)
- Create a sub-sub-folder named 'raw" (F:\Year2017\October 31, 2017\raw)
- Copy the files from camera SD card and iPhone to the new 'raw' folder
- Open Lightroom and Import the new folder/sub-folders and photos
- Add location (GPS) data to files that don't have it
- Select all (ctrl-a) photos in the new folder (F:\Year2017\October 31, 2017\raw)
- Export as DNG to a new folder named 'dng' (F:\Year2017\October 31, 2017\dng)
- Right-click the 'raw' folder and choose Remove, to remove this folder from Lightroom
- Add star ratings, color labels and keywords to the files in the 'dng' folder
Here is a list of what I find happening in Lightroom:
- Files from one folder that are exported to a new folder loose most of their keywords. Example: If I Export files as dng from folder 'raw" to a new folder 'dng' and their were 5 keywords attached to these files. The newly populated 'dng' folder would have the first or maybe the first couple of keywords attached to its files. The rest are not copied over to the new files.
- As stated above (workflow) I work with files in the 'dng' folder under the date and year folders. After Lightroom Classic converted the catalog I found that many of the Lightroom folder pointers were off. That is, instead of the folder (F:\Year2017\October 31, 2017\dng) showing in the folder list, it was back to (F:\Year2017\October 31, 2017\raw). This forced me to Synchronize the folder for that date, to give me both the 'dng' and 'raw' folders back. Then right-click > 'remove' the 'raw' folder again. The keywords, color labels and star ratings were all intact in the 'dng' folder.
- If I select a series of photos and apply a label, keyword(s), etc., this new information is, sometimes, applied to only the first selected photo. I then have to go to each of the other photos individually to apply these attributes. Other times, like yesterday morning, I tried this and the attributes were applied to all selected items. Can't tell when this is going to happen.
So, I am done testing for the time being. I don't have the time nor inclination to deal with this right now. I will retire Lightroom Classic for a few iterations (versions), then maybe try it again. Hope this information was helpful.
Thank you for helping we get Lightroom 2015 reinstalled.
