SUMMARY: Moving A Complete System To An Other Machine

Well, i don't know if this summary is relly something interesting for
sun-gurus, but here it comes.

First of all, a special "THANK YOU" to:

Edward C. Zimmermann <edz@bsn.com>
Dylan Northrup <northrup@loudcloud.com>
Rick Dipper <rick@UnglaublichIT.com>
Ric Anderson <ric@Opus1.COM>
Bill Mooney <bmooney@seflin.org>

Here is my original question:

-------------------------------------------snip-----------------------------
-----------------
is it possible to move a hard disk with a completely installed Solaris2.8
from one U5-SPARC-machine to an other which is absolutely identical
(identical hardware)?
Is there something i must re-configure before or after such action? All
system and network settings would be the same, but would Solaris2.8
re-configure itself automatically from the hardware-ids and so on?
-------------------------------------------snap-----------------------------

ok, there seems to be an easy and a hard way. I'll take the first one,
because that's the way i would have chosen if i didn't post my question.
Most of you said, it's ok just to swap hard disks - i'll try it tonight
(DE), we will see ,-) If the new hard disk has been swapped, boot -r would
do it - that's the easy one!

Main issue is with early U1 where
one sets a flag, by default, to run the kernel in 32-bit modus due to a bug
in the processor that can hang on a specific sequence of instructions.

Also, make sure that all the
peripheral cards (i.e. qfe cards, scsi cards, etc) are in the identical slot
on the new machine as they were on the old).

Bill's way seems to be the hard one and it's surely perfect if you want to
clone a system:

-------------------------------------------snip-----------------------------
------------------
ufsdump each partition on original machine to tape.
boot new machine from CD-ROM.
partition disks in new machine like the original.
ufsrestore each partition to new machine.
use "installboot" to install boot block.
reboot.
Note: the new machine will have same IP, etc
as old machine so you should do a "sys-unconfig"
to reset these.

Here a tip from Ric:

-------------------------------------------snip-----------------------------
-----------------
If you have licensed software (e.g., Forte C compiler, Mathematica, etc.)
then those applications will not work until you get updated license keys
based on the new hardware ID.
