We have a situation where we need to migrate some Solaris 2.6 servers
to Solaris 8 "brandz" zones. The idea was to LiveUpgrade 2.6 to 8,
then create a flash archive of the 8 environment for moving to a
zone. The problem we have is that the 2.6 servers are completely out
of physical disk space and, due to various reasons not worth going
into here, it is not feasible to attach more physical space to them to
facilitate a live upgrade. It *is* possible to NFS mount more storage
to each server, though.

Given the above, how would you handle what we need to do? Is it
possible to liveupgrade to an NFS mount? If not, is it possible to
LiveUpgrade directly into a flash archive? If not, and LU is looking
for a "physical" device to upgrade to, can something like iSCSI be
used to "fool" it (and I wonder if iSCSI even works on 2.6)?

I fear the response I'm going to get is "ufsdump everything to the nfs
mount, then restore onto a server that has extra space, then
liveupgrade, then flar" but we were hoping to avoid that because the
source architecture is rather old (ultra 1/2/5) and I'm not sure we
have any of those left over here to restore to.

All advice/criticism appreciated!
