No, you have to duplicate flash and EEPROM from the old MCU to the new

Exactly you need to copy full flash+eeprom or it wont work.

Remember to heat the mcu before reading, and read/verify a couple times to make sure it is well read.

Also when buying from ebay.com make sure you look at estimated delivery :p
