That's what I also noticed. Unfortunately I changed to TP8 several thousands pictures ago. Going back to any TP7 previous database backup is no option.
Currently, I'm on my way using MS-Access to generate a plain textfile with all information (keywords, galleries, annotations) I need. This textfile I will use to add to the metadata. (Current plan is probably using exiftool).
This consumes still a lot of time, but I assume less than tagging again.
Thanks anyway for replying
Best Regards
