All,
We are physically moving a disk volume from a 760 to an 840 tonight. We're resonably confident about bringing up the 840 with the moved disks on it. The volume will come up as a foreign volume (it won't need to be renamed) and we'll just need to do a "vol online" command for it. It's not a root volume.
However, the book says to check "your hardware guide" for instructions on removing the disks from the 760. We can't find this anywhere. Our current plan is to remove references to the volume in the various /vol0/etc files; shut down the 760, power it and it's shelves off. Remove the disks and just power everything back on again.
Is it that simple?

Yup. It is as easy as that. Don't forget to bring over all your quota, export, and CIFS share information for that volume.
Be aware of the 18GB spin-up issue though documented in Field Alert 55 and explained in detail on the following FAQ:
http://now.netapp.com/NOW/knowledge/contents/FAQ/FAQ_1088.shtml
If you have any of those drives, they may not spin-up when you power them back on. Furthermore, our experience was that not all of the defective disks can be repaired through the procedure listed in the FAQ above.
The moral of the story is that a good, recent backup of your filesystem is always the best way to start this kind of project. =)

FYI:
It was that simple.
The move went without a hitch. Thanks to Paul at NetApp for pointing out that the boot image on the moved disks would be wrong (the 760 is alpha and the 840 is intel). A simple "download" command fixed that. We didn't have to boot from floppy because the disks added to the 840 were way up there on the chain.
Thanks to all who replied.
