I was running LR 4.4 on a Vista OS. I purchased a Win 8.1 computer. Per an online tutorial, I transferred my photo folder to the new computer then installed LR 4.4, then transferred over the .lrcat folder. The catalog cannot find the photos. Is there something I am missing or a different way to accomplish this? I intend to upgrade to LR5.7 but thought that it would be simple to work with the same version between computers and operating systems. Any step-by-steps or advice would be appreciated. Thanks.
