First remove sata ssd running Win 11 from new 8900, next install nvme ssd in new 8900. Try to see if it boots. If old and new 8900 have same bios sata operation setting, either AHCI or legacy, new 8900 would boot smoothly from old ssd. If sata operation setting is different between the two 8900, it will give error. In that case need to enter new 8900 bios to change sata operation to the same as old 8900.
yes you can not install Win 11 on a 8900 (not officially) but Win 11 installed elsewhere does not stop itself from running in 8900 after transplant. there is no rejection. Install and run are different processes.
