I upgraded my PC to Windows 8.1. I have a Lightroom 4 catalog and I have the Lightroom Photos directory for it. For one thing the Lightroom Photos are no longer on the same drive, so the reference to that drive won't be correct in the catalog.
My goal is to import this catalog into Lightroom 5, because is has keywords and so on that I would like to preserve.
How can I import this information into Lightroom 5?
Thank you for your help.
