Migrate WSUS server from 2003x86 to 2008x64, new hardware, use same name and IP address?

Question

Searching through the WSUS forums and reading the TechNET migration documentation, I have bits and pieces of information to make this a smooth transition...I think. I have a plan in mind but
would like the communities input on what I am thinking before moving forward and having it blowup in my face :). <o:p></o:p>
I have the following currently:<o:p></o:p>
A single WSUS 3.0 SP2 server, running on Server Win2003x86, using the default WID (susdb.mdf) on the same server. I have SQL 2005 Express installed on this server as well for other services
but this has no bearing on the WID correct?<o:p></o:p>
What I would like to do:<o:p></o:p>
I have a new server (a much better one) that I would like to move WSUS on to, that will be running Server Win2008x64 (I have to setup first). <o:p></o:p>
Steps that I would like to follow:<o:p></o:p>
1. I will go through and setup this new server with all M$ updates etc... under a new name (ex. wsusnew) and DHCP acquired IP address and then power it down. <o:p></o:p>
2. Get on my current WSUS server and backup all current WSUS settings, groups, DB etc... to a network location for temporary storage. Then power it down.<o:p></o:p>
3. Delete the current WSUS server computer object in AD, DNS entry I will leave because my intension is to give the same IP address to the new WSUS server.<o:p></o:p>
4. Start the new server, static assign the IP address from the old WSUS server to this new server and then change the name of (wsusnew) to the old servers name, which should be ok sense I deleted
the AD object in step 3.<o:p></o:p>
5. After the obvious restart, the new server will have the same name and IP address as the old server. <o:p></o:p>
6. Now that the new server is up (with same settings name/IP as old server), I will then go through and install the WSUS role on the server and restore my WSUS information.<o:p></o:p>
Questions:<o:p></o:p>
1. Step 2 above, is it possible to do this, without making replica servers? I kept reading about this as I was researching doing this, I would rather just copy the DB and folders and simply
put them in-place on the new server.<o:p></o:p>
2. Step 6 above, restoring of the data, what is the proper way to do this in the scenarioI described? <o:p></o:p>
Thank you to anyone who can provide me some information.

Thank you for the reply, I will follow and let you know. Proabably be next week sometime before I'm able to try though. So look for a reponse then. Thank you again.

OR...
You can use the much more simple, much more reliable, and much more proven method of:
Install new server as a replica of the old.
Replicate.
Configure new server as upstream server.
Point clients to new server.
Turn off old server after all clients have redirected to the new server.
For everybody that has tried the backup/restore the database procedure described above, they have encounted complications of one form or another.
WSUS has a built-in and fully supported comprehensive replication capbility. use it! :-)
