Yes I'd done some test upgrades on systems with ZFS and it seems to go 
like a dream compared to UFS and messing about with slices etc. I will 
go  ahead on friday and do the re-install of our fileserver, I did a 
test on VMware and it worked like a charm, my test pool was re-imported 
perfectly.

I think I will follow your advice and pull the pool disks until the OS 
is re-installed, I guess you can never be too careful :)

Once the system is on a ZFS root I will be confident to perform future 
upgrades with the live upgrade tools as I've tried that both on UFS and 
ZFS and the latter is a hundred times easier.

Thanks for everyone's advice

Matt
