Mac SSD Upgrade from OEM to NVME SSD

Thread needs solution

Has anyone upgraded their mac's hard drive to an NVME SSD and cloned the old drive to the NVME?

I have a Mid 2014 MBP Retina (11,3) - I recently bought an OWC 2TB NVME Aura x2 and time machine fails.

I'm wondering what will happen when going from the PCI protocoled SM1024F to the NVME Aura X2.

To do this upgrade, I need to install the NVME, then put my SM1024F into an external enclosure. Then I'd need to clone from the USB to the NVME. I need to do it this way as recommended by OWC, and to use the supplied SM1024F USB drive enclosure.

If I bought True Image 2019 - would I create a bootable USB, then use Option to boot to it, and it'd do the cloning?

Additionally - I have a bootcamp partition. Would I do better NOT to clone that, or should I clone the whole thing, bootcamp included?

Any advice is greatly appreciated.

I haven't tried this on a Mac.  However, keep in mind that a clone is an EXACT copy of the existing drive (and OS) which includes the existing hardware and installed drivers.  So, if cloning SATA to SATA, you'll be fine.  However, a clone from SATA to NVME PCIE is different hardware and not likely to boot because the OS is not prepped for this hardware difference and you're trying to make an exact copy "as is"... hence, a clone of what's there at that point in time.

#1, I would make a time machine backup to start and give yourself a recovery option - just in case.  But you're going to be smart and safe by doing the next steps as well, so the TM backup is just a precaution.

#2, I would install the PCIE NVME drive into the system as a new, secondary drive.  Ensure the existing booted OS can see it and initialize it and format it as Mac OS journaled.  If the existing OS can see it and detect it, chances are drivers are installed and ready so when you migrate, they will be good to go.  You may want to boot into bootcamp and check it is detected as well (although, not likely if the entire disk is formatted as journaled initially at this point.)

#3, after that, I would install the Acronis True Image 2019 trial and do a full disk backup (not a clone) to an external USB drive.  Then, do a full disk restore to the PCIE NVME drive.  This backup and restore will copy the entire disk (must be done from the Mac side) including the bootcamp partition, but also prep it for the hardware change. And, if your bootcamp is Windows 10, migrating to PCIE NVME should be OK since it has native support for these drives.  If windows 7, it's not going to boot and you need to apply hotfixes first to the Windows side FIRST and you should test it after the hotfixes just to make sure it's detected and accessible.

Anyway, once you've taken a full disk backup, be sure to physically disconnect the main SATA drive.  Then Restore the backup to the PCIE NVME drive.  Then attempt to boot it on the Mac OS side... assuming all is well, then try the bootcamp side.

The key to any migration is that you don't want two "like OS installs" connected internally at any given time or you may bork up the bios with a disk collision where it thinks both are the same disk.  And if things don't go as expected, then you can disconnect the NVME drive and plug back in the SATA drive like nothing changed.  You could then try to restore your time machine backup to the NVME drive as well with little risk.
