We just got our new F840 (it has an UGLY *gold* faceplate by the way). It will be replacing an F740 straight away. My questions have to do with swapping an Intel NetApp for an Alpha NetApp while keeping the same disks. Has anyone done this yet? Aren't the Ontap system files different binaries?
What should the sequence of events be? Our plan (so far) is this:
1. Shut down the 740 2. Boot from floppy of old OS (5.3.6R1) 3. run a wafl_check (we want to do this anyway) 4. still using the 740, upgrade using the 537R1_sysfiles_i.tar file (I'm presuming these Intel binaries won't work on an Alpha NetApp) 5. on the 740 console, run the "download" command (will this work now?) 6. disconnect the 740, pulling it's Gigabit ethernet card 7. Put the gigabit card in the 840, connect it up 8. Turn it on and it will work (right?)!!
Any thoughts, comments, will be appreciated.

If you go to NOW, you will find upgrade instructions for a head swap.

Indeed. I did a search on Knowledgebase for "upgrade F740 to F840" and up it came. (I should heave done that first.)
Solution ID: 3.0.6869703.2865011
We swapped a F720 with an F840. Life was a bit easier since we had a seperate volume just for the Ontap on the 720. After transfering the neccessary cards from the 720 to the 840 we built a new volume on the 840 with the new required OS ( we had enough spare disks, and an extra shelf). We then connected the shelves from the 720 to the 840 (without the disks that had the old OS on the 720). We then did a disk firmware upgrade. We had to reboot most of the hosts - the NFS hung I think due to the change in the MAC address of the new Giga card we added. I think that sums it up. It took us about 60 minutes.

All looks right -
It is not necessary to do a wafl_check but you know that already - you are just going from alpha to intel based processor.
the only thing I would add would be to take a snapshot before you do the "download" command. Then you will have an exact picture of the FS before the upgrade you can revert back to if necessary.

Just to let you all know, the swap went very well Friday night. We followed the previously mentioned NOW article (Solution ID: 3.0.6869703.2865011) with no problems. The only differences were running a required disk_fw_update after the 840 reboot. Also, the original fibre channel card from the 740 wasn't supported in the 840. Fortunatley the 840 we got came with it's own FC card. However, it wouldn't go in slot 1, like we had on the 740 because it is a longer PCI card. This forced all the disks to be re-numbered, but it came up just fine.
Also, the 840 ran a parity recalculation on all the disks. (Perhaps caused by the disk re-numbering?). This was a bit unexpected, and slightly panicy as all the disk lights were going nuts after we brought the 840 up. But the filer was serving up volumes just fine, so we trusted "The Force" and let it go. It finished a few hours later and all is well. We even added a new tray of disks to get us over 1TB!
Thanks to all who responded.
