Relocating feral cats should be undertaken only as a LAST RESORT after all other alternative are exhausted.  Because feral cats bond strongly to both territory and their caregiver, it is best to leave the cats where they live.  Ferals become well-adapted to their territory and can live safely and contentedly in a host of locations.  Relocating a feral colony can open up a void that allows unneutered cats to move into the area starting the cycle all over again.  Below is some resources about relocating feral colonies that might be helpful.
