I upgraded to LR6 just yesterday - I have been using LR2 for several years (...obviously...). The installation was smooth except I believe LR6 installed my old LR1 catalog, not the LR2 catalog that is most current (seven years worth of photos missing). Can I upload/install the LR2 catalog into my new version of LR6 by some other means?
Open the Old Lightroom2 catalog with Lightroom 6.
Go to the location where your Lightroom catalog is located
Right click the Lightroom2 catalog>Open with>>Adobe Lightroom.
Else go to Lightroom>>File>>Open Catalog
Open the Lightroom2 catalog
Hope this helps
Akash - thanks for your help - worked perfectly!
