Cyclone and other device in intel FPGA have lot difference , from the core power supply voltage , numbers of LABs , Number of Logic Elements etc…
Example even the core power supply to the Cyclone from other devices wont be the same. Similar to above example there is lot of
difference in IOs.
Sorry , There is no migration document from Intel for these devices .
I am not also aware your design to suggest optimized part.
I would recommended if you plan to redesign the board you can look for new devices in Intel FPGA such as Max 10, Cyclone devices or Arria devices which has more longevity
Can you let me know any other way i can help you out ?
