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!

I assume there's a sound reason you can't go straight to Solaris 10?

I'm sure LU requires a physical device. I'm not sure if LU was present
in Solaris 8...

Can you get hold of an old external SCSI drive box to use with the old
systems?

The application doesn't work in 10 due to library changes and other
miscellany. It does work in 8, however.

It's not; it's expected that you mount an 8 CD/DVD and install the
packages. Best practice for LiveUpgrade is to always remove then
reinstall the SUNWluu and SUNWlur packages from the distribution
you're upgrading *to*.

No, these are in a remote location.

OK, I was wrong there, you can Live Upgrade from 2.6 to 8 on Sparc.

You might be better off with s clean Solaris 8 branded zone and
reinstalling the applications.
