My Orginal question:
I need your advises. I have planned to swap the OS disk from my E3000 server
to my Ultra 2 server this weekend. At the same time, I intend to swap the OS
disk from the Ultra 2 to the Enterprise 3000.
Both machines are currently running the same OS, Solaris 2.6 and patches.
May I know can this work? If anyone of you have the experience, please
Your help are deeply appreciated.

According to David Evans

I'm going to put out the disk and just swap it. Even if they are both
machines are the same architecture, I still have the issues of what devices
are attached and how they have been installed (see path_to_install for more
If they are the same architecture, have the same devices installed and
all the devices installed in the same order it should work. Unless I'm able
to force things into place if there broken.
Advise from David is that I should back up the disks, swap the disks and
reinstall the OS then recover any files needed.

some hardware differences which will not be catered for,
e.g. the path_to_inst stuff for mapping disk drives is different, as is all

You have to boot on the net or on a cdrom and do the following:

echo "/usr/bin/tar cf - devices | (cd /a; tar xpf -)"
/usr/bin/tar cf - devices | (cd /a; tar xpf -)
echo "cd /cdrom/Solaris_2.6/Tools/Boot"
echo "/usr/bin/tar cf - dev | (cd /a; tar xpf -)"
/usr/bin/tar cf - dev | (cd /a; tar xpf -)
