If you perform an "image" clone on a TPM encrypted drive, it will only be readable by the system with the TPM that encrypted the "source" drive.
Right. But, here I am not moving anything to a new platform.
It does occur to me that I did not try to copy / paste any individual files from C: (the eMMC “OS” drive) to D: (the new SSD). (My tests on “D” were copying a few files onto it from a USB stick, and then opening them, then deleting the copies.) But, in the past I’ve moved files from C: to a micro SD card I’d put in the laptop’s micro SD port semi-permanently for data storage, with no problems, and ditto for files transferred to a USB flash drive in any of the USB drive ports.
