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.

Subject: Upgrade from F740 to F840

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?
