Upgrade from 2TB fusion drive to genuine Apple NVME ssd?
I have a 2017 5k iMac with 2TB fusion drive fused with 128gb nvme ssd. I was wondering is it a simple plug and play replacing the 128gb nvme with a 1 or 2TB genuine apple NVME say pulled from 2017-2019 5k iMac? I also plan to replace the 2TB HDD with a SATA 3 2TB ssd. What else do I need with the SATA ssd to replace the HDD?
