Re: BMR - unlike hardware

This is interesting, since my experience has been that we have had more success
with W2K than W2K3 (using the copy-out/restore/copy-back you describe). I
always seem to run into a brick wall with the way W2K3 does it's
replace-on-reboot for system files being restored. Maybe I'm trying to copy
back too early or too late - can you provide some detail on what is working for
you?

While the recovery console could be used you can also choose to copy the files
out, perform the restore and then copy the files back before you reboot. You
only need to use the RC if you forget to copy the files back before you reboot.
I've posted the use of the "in-place" upgrade many times to ensure the new
hardware on the new server is properly enumerated. Still, I always use the
approach of copying out the files and then back in after the restore first.
With windows 2000 I've found this works about 80% of the time, with Windows
2003 almost 95% of the time. For the time when it doesn't work the "in-place"
upgrade does. For that process you do not have to use the RC at all to copy any
files first.

In my mind, the MS Recovery Console is the key to achieving successful restores
back to dissimilar h/w in the Wintel area. After installing your vanilla MS OS
(that is to be restored over), you need to take a copy of the OS files that are
specific to your h/w. Then, if they are overwritten with different versions by
your restore, you can put them back with the RC upon reboot.
These files can be found in Device Manager--> Computer and then under the
driver details of the Properties of your processor(s).
For Windows2000, they are as follows
c:\winnt\system32\hal.dll
c:\winnt\system32\kernel32.dll
c:\winnt\system32\ntdll.dll
c:\winnt\system32\ntkrnlpa.exe
c:\winnt\system32\ntoskrnl.exe
c:\winnt\system32\win32k.sys
c:\winnt\system32\winsrv.dll
For Windows2003, they are as follows
c:\windows\system32\hal.dll
c:\winnt\system32\ntkrnlpa.exe
c:\winnt\system32\ntoskrnl.exe
If after you complete the restore of your system drive and you reboot and get a
blue screen or worse, all is not lost. The Microsoft Recovery Console is an
extremely useful tool. From the RC, you can copy the above original files from
a floppy or the root of the system drive to the
system32 directory. Also, the RC will enable you to disable devices or services
on boot.
One important point to note, the RC requires the LOCAL administrator password
to be entered before it can be used, therefore ensure that you know the local
passwords to all your machines.
The following IBM Technote is also very useful for Wintel system restores

Above all else, the key to restoring back to dissimilar h/w is practice.
Where possible, try to trial restore as many of your Wintel systems back to
unlike h/w. I know it is obvious, but it is far easier to solve any arising
issues in a DR trial environment, than at 3am with somebody looking over your
shoulder, asking every 5 minutes when will it be ready ?

>What kind of system are you concerned with?
I'm looking for some basic info on all platforms anyone has experience with,
Windows being the biggest concern. After hearing some remarks this morning in a
meeting concerning bringing back a server from scratch, and how long it took,
I'm flabbergasted. Then again nobody called me to ask for help either.
To add to this are there any issues anyone is aware of for servers that have
been virtualized but still use TSM for their backups? Would the process be the
same?
Thanks,
