Hello,
I'm doing a 6070 to 6240 head swap, with the 6070 at 8.0.1p5 and the 6240 currently at 8.0.2p4. Due to some critical issues with 8.0.2p4, I need to get both controllers up to 8.0.3 or 8.1. I know I can upgrade the 6070 to whatever version we decide on, then head swap as usual, netboot the 6240 to that same version, reassign disks and destroy mailboxes, then netboot again and upgrade. However, I'd feel a bit more comfortable with the process if I could upgrade the 6240 ahead before the head swap. Is that possible via netboot and the maintenance mode environment, or does the ONTAP upgrade require a root volume?
Thanks.
