Best way to migrate to new machine w/ min downtime.

I need to migrate a client from one machine to another. The problem is that the machine is online (pun intended) all of the time, so they can only afford a minimum of downtime. My thought is that I need to run a level 0 archive, load that onto the new machine, then just before we're ready to cut over, take the old machine offline, bring the logs over from the old machine to the new machine, roll them forward on the new machine, then bring the new machine online. My concern is that certain utilites seem to be chunk or page specific. The new machine will not have the same partitioning as the old machine. So I need to avoid any utilities which would rely on such specifics. Which backup utility would be best in such a case? I believe that Ontape is not usable because it tries to restore to the same device, (these will be different on the new machine) correct? Unload and Dbexport don't keep logs after running, so I can't do a roll-forward. Is OnArchive the choice in this scenario??? Thanks for any help. -- * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * Blah Blah Lounge - "Do You Have Something Smart To Say?"
