Sorry about that!

Right now I'm trying to do this with Solaris 10 update 10 on VMWare, but I am looking for information that would apply to SPARC machines too.

UFS filesystems.

Looking at your profile and posts so far on this forum I cannot tell you whether you have the knowledge to do this. Can you give a clue as to your skill level. You say that you've laid out a copy of the filesystems?
Please consider me a novice! I have a rudimentary understanding of Solaris and filesystems.

And I have laid out a "copy" of the filesystems on my new VM in the sense that I have created filesystems (/opt, /, etc.) on the same slices as the original machine and I have tried to create them the same size as the original VM but I might be off by a few megabytes.

What I'm saying that it's probably do-able but can be tricky. I'm sure we can provide the missing pieces of the jigsaw if you have the experience.

And also, what media is your backup stored on? A tape drive that you're going to attach to the new platform, a remote (nfs) node, or what?
I've backed up my files using some backup application that I'd rather not name at the moment. It is stored on our backup server.

What I did was install a new version of Solaris and copied over my old files to some directory (lets say /restore). Then I booted Solaris off of the CDROM into read-only mode and mounted my root filesystem to "/a" and then I went inside /a and overwrote all of the existing directories (/boot, /dev, /opt, etc.) with the files from my backup, and I'm sure those more familiar with Solaris will tell me it was silly to think this would work, which it did not. I'm guessing I shouldn't overwrite directories like /boot and /dev.

So assuming my backup contains *all* files that were in my previous system, is there a way to restore these files onto a new machine and have more or less a copy of my old machine?
