You need to transfer the SSD data to a new NVMe storage device. Since you can't connect the NVMe drive directly to the old PC, you'll have to link the old SSD to the new one. After setting up the new system, ensure the BIOS recognizes the SSD by updating its boot settings.
The old storage devices were SATA and mSATA interfaces. Regarding the PCs, I can provide details about their motherboard models. The new motherboard configuration does not disable SATA ports when an M.2 SSD is installed.
Your SSD likely uses the MBR format, since the device running it is more than 12 years old and lacks UEFI support for GPT, or it was configured to mimic older BIOS settings. UEFI requires drives formatted with GPT BIOS, while MBR needs BIOS support to boot.
