The application doesn't work in 10 due to library changes and other miscellany. It does work in 8, however. > I'm sure LU requires a physical device. I'm not sure if LU was present > in Solaris 8... 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*. > > 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. > > Can you get hold of an old external SCSI drive box to use with the old > systems? No, these are in a remote location.

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