I have Lightroom 4.4 on my computer and upgraded to Lightroom 5.7 64-bit. I would like to know how to tranfer my pics to 5.7 and then uninstall 4.4.
Simply open the LR4 catalog with LR5. It will create a copy and upgrade the copy of the catalog for the use with LR5.
The LR4 catalog will stay as is.
