I recent bought and am using Lightroom 6, now want to buy the Photography package from Creative Cloud. Can I transfer all of my catalogs and settings from LR6 to LR CC?
Lightroom CC will use the same catalog as you have been using with Lightroom 6. All of your presets should be visible just as they are now. The only thing you need to do is switch to Lightroom CC. I don't think that even requires a reinstall, but I might be wrong. I have never used Lightroom 6. I think all you need to do is install the Creative Cloud Application Manager and sign in.
