I am trying to move my LR CC catalogue to a new disk. I am moving the Lightroom Catalog file and the Lightroom Catalog Previews.IRdata folder and then right click on the Lightroom Catalog file and try to open in LR. However I get an error and it does not open. I have done this with previous versions of LR in the past and my recollection is that this method works. However it does not work this time. Am I doing this correctly or are things different in LR CC? I am running Win 8.1 and am moving the catalogue from a (full) 256GB OC SSD to a 600Gb Intel SSD. Any thoughts appreciated.
