If you want to do this with minimum pain, get some extra disks, install the
OS onto one new disk, get your existing system disk partitions mounted on
your new disk, use the OS on the new disk to do the backups (to another new
disk) and then do the restores.  You *can* do this running off of the CDROM
but it's way painful.  In fact, you've got lots of free space, apparently.

        What you want to do is little different from having to
        restore a system disk backup after losing a disk.  You
        can use the standalone system on the CDROM to restore
        the root file system.  You can either use it a single
        user booted root to restore /usr.  There might also be
        other guidelines in the system management documentation.

I can now begin working on this in earnest.
Thank you!

ORIGINAL QUESTION
=================
> Hi,
> 
> We recently upgraded a 4100 from 4.0E to 5.1A PK1 (through all the
requisite
> intermediary releases).  Now I'd like to convert the AdvFS domains to
> Version 4.  I understand how to do this conceptually (full backups, drop
the
> domains, recreate the domains, restore the data).  My question is how to
do
> this for the domains that have the operating system on them -- if I drop
the
> domains where the OS lives how do I then use the system?  Do I boot off of
> CD?  If so how do I sequence the various events vis-a-vis booting off CD?
