I Have mistakenly worked on files in a catalogue connected to a version of lightroom 4 I have installed on my computer, and also on a catalogue connected to a version of lightroom 5 installed on my computer. I would like the catalogue in lightroom 5 to reflect the changes I made to files in the lightroom 4 catalogue. How do I do this?
Open Lightroom 4, select the desired photos, then File->Export as Catalog (give this catalog some name, do not check "Include Negatives")
Open Lightroom 5, select File->Import from Another Catalog, and point to the catalog you just created using LR 4
