Merging LR3 and LR4 Catalogues?
Is there a way to merge Lightroom 3 catalogues and Lightroom 4 catalogues all into 1 catalogue?
It's driving me nuts having to relaunch/reopen a new catalogue every time I want to access different images. In some cases some of the pictures were taken only weeks apart - between LR releases.
Thanks for any help or feedback.
