How to copy the content of EPROM 27C256 to EPROM 27C512.
 

Surely you just "read" the first device, replace it with the second device, change the device part number and select "program"? You may need to save the "read" data to the PC in between if the software clears the memory on a device change, in which case you then need to reload the data from the PC.
