Supersede original reference with latest version before relocating library
I have a relatively large library that was initially on iphoto with a tiny hard drive. As it expanded I ran out of space and chose to delete all the un-rotated originals to cut down on the space it occupied. this was a success with no repercussions until today.
I now am in a situation where Aperture can't find the originals and I therefore can't relocate masters on to a NAS (whilst keeping the library on my laptop) as I have run out of space gain and wish to store the photos all on the network as opposed to the laptops drive - I am also about to upgrade my laptop to one with an SSD which is smaller than the HD that I currently have.
Any suggestions?
