We have a number of machines (30+) that we will only use LU on to update
existing releases and will (as a matter of policy), do a fresh install when we
go from one update (i.e. U8) to another (i.e. U10).

As out "mis-management"
insist on minimizing disruption to end user processes but won't fund
sufficient systems to deliver that, this is the only time we get to do any
re-work on machines so they reflect more modern techniques like ZFS mirrors
for boot/root when before everything was plain old UFS and prayer that no disk
drives would ever fail, and update things like drivers for Fiber HBAs and so

and U9 installs directly to U10 or if I want the installs to be closer in sync
with each other (as far as installed packages/patches, etc), should I
technically bring the U4 installs to U9 first then go to U10?
far as Solaris 11, we have a number of unsupported boxes (Sunfire 4800, V880,
