I think the best solution for this is to do:

1. Make a  mksysb tape on original server

2.  On new server, boot off AIX CD  and select (I forget exact menu 
nomenclature) not regular mksysb restore but Recover from etc, etc. (Check AIX 
Install manual or if you have experience wander through menu.)

3.  When you get to select device for mksysb restore THEN insert your mksysb 
tape and restore.  (You can select specific disks to use for rootvg if you 
want).

As you are going to different system type and probably at least some minor 
hardware this will use mksysb tape BUT when it finds it needs some code that is 
not on mksysb tape it will pull it from AIX CD.

After system is back up then you can setup non rootvg filesystems and restore 
that data from ADSM.

        Does anyone know of a Redbook or manual that would cover recovering
an AIX server to a different server type? We will be migrating SP widenodes
to rackmounted M80s. All the systems have external SSA excluding the
rootvgs.
        My concern is when we attempt to restore the rootvgs. Will we have
to manually go though and restore some system files while skipping others?
Our rootvgs hold /, /usr/, /etc/, /tmp/, and /home/.

        We haven't started anything so even suggestions on preventive
measures would be appreciated!

Thanks in advance for any assistance.
