I'm contemplating the purchase of an M2 Ultra Mac Pro. Will a StartUp SSD, from my current Intel NcMP 7,1, with Sequoia 15.5, boot on the newer Silicon Mac Pro 14,8?
My hunch would be that the OS is now a single fat binary, so that it can have its hash compared back against a version at Apple. If they were doing lean installs for the spacific chip, of model etc, the sealed system volume lookup would be impossible.

Don't quote me on this, but most likely it will but you probably need to use the Apple configurator to wipe it and install macOS on it.
If you want to "transfer" over as well, I suggest backing it up first to another drive, then when the SSD is moved over and installed, you can then transfer over the OS.
^^^^I solved the problem. I don't use Time Machine. To initiate the new Silicon Mac Pro, I used Migration Assistant to transfer from my old Intel Mac Pro. I then used CCC to clone the Mac SSD to one of my backup SSDs.
BUT, things would have gone a lot quicker if I could have booted from my Intel OS backup to the Silicon machine🫢
