If you didn't notice it at the My Autosupport page, there is a script they recommend named aggrspacecheck. When you convert to 7.3 it moves the meta data for snapshots from the volume into the aggregate. This will make sure you have room in your aggregates for the upgrade. If you don't have any aggregates over 95% full you should be fine anyway.

Yeah, I thought of that. I want to try upgrading the disk FW in the background during off-peak hours before the actual OS upgrade to shorten that.****
I thought of going to 7.3.X first, but the requirements between that and 8.0.X don’t seem that different. This is a single filer with 8 disk shelves.
I have run the Upgrade Advisor under My Autosupport on the NOW site, and it does provide very comprehensive guidelines and instructions. Highly recommended!****
Thanks to everyone for the input!****

Alexander’s post made me think of one more thing – the more disks you have the longer it will take to update their firmware. For a heavily loaded filer it can take quite a while.****

Hello Moshe,****
I would definitely do the upgrade in two steps if possible – but that’s just because I’m paranoid.****
So I suggest upgrading to 7.3.6 first since there are quite a few things that changed from 7.2 to 7.3 and once that’s done, continue to 8.0.2.****
Can you plan downtime for the whole upgrade? Are you running a Metrocluster or is this a single system (local cluster)? How many disk shelves?****
Are you planning to use 64bit aggregates after the upgrade too?****
Bye,****

We are currently running 7.2.6.1P9 on our 3160, and I want to upgrade to 7.3.3 or later. Any reason not to go all the way to 8.0.2? My hardware is all supported (finally got rid of those old disk shelves). ****
And if we’re upgrading, do you usually upgrade disk and shelf FW as well? Is this a requirement? I seem to be one version behind on most of my FW right now.****
Thanks,****
