Fairly straight forward. There is documentation out there if you search the NOW site. I have it but, it's on my other PC. I'll send it to you when I get a chance.
Basically, all you do is an OnTap upgrade. Just unzip the new system files, not the boot disks, in the /etc directory, enter "download", halt the Filer. Swap heads and boot up. Be careful about things like NIC slot numbers, hostnames, netbios names, ip addresses, DNS, NIS and things like that. Other words, if you're using the onboard ethernet on your 740, its name is 'hostname'-e0. If you go to Gb-E or even another 10/100 port on the 840, your host name will change to 'hostname'-e8 or something.... This may screw up your DNS and possibly NIS. So, my point is, review the entire config and think about what may change and the possible ramifications.
Hope that helps.

Hi!
I intend to upgrade from F740 to F840. I will only swap heads and keep the disks. I can't seem to find document describing this procedure. Any body done that? How do you change ONTAP from Alpha to Intel version?
Regards, Uros

So it is possible to install the Intel kernel (for the F840) on an Alpha system (the F740) and have it write the Intel bootblocks to disk? Is this officially supported? It sure would be nice to skip the interim floppy boot stage when swapping filer heads.
Anything else to watch out for if you are swapping an F740 running 5.3.7 with an F840 running 6.1.x? ZCS vs. BCS drives? I assume DOT will "do the right thing". Do quotas need to be rebuilt?

No, I think Todd is wrong here and Jay was right in saying that you need to create and use floppies. "download" will use /etc/boot/*-alpha if it's running on an alpha box and /etc/boot/*-x86 if it's running on an intel one.
Maybe by foul means you could fool it into copying the "wrong" files to the boot area, but this would be burning your boats in a big way. If the new head fails to work, you would no longer be able to retreat to the old one except by booting from floppy --- and if you're prepared to do that, what's the big deal about making new ones?

Whoever it was the one that stated you could download the Intel Ontap kernel to an Alpha box is correct. I have done this 4 times now, where I download the Intel version of Ontap to an F760, halt the filer, swap heads, then boot. It does work exactly that way.

Our F740/5.3.6R2 -> F840/6.1.1R2 upgrade happened this past weekend and everything went smoothly. I did confirm that you can't "trick" the Netapp into loading the wrong bootblocks for a particular processor architecture. I tried renaming the files and symlinks and so on, but the filer would complain about "wrong format" when I tried to download the boot blocks. So the bad news is that you do have to boot off floppy. The good news is that the Netapp prevents you from shooting yourself in the foot. ;-)
