ide raid 5 to sata raid 5

My Webserver at work is in need of updating. Currently it runs two
Raids, a mirror for data and a raid 5 for OS, hotswappable. The raid
is all IDE, using a promise raid controller and samsung ide hard
drives (60 gig drives).
I want to move to sata with as little downtime as possible.

Can I do this:

1. remove current OS HD's
2. put in sata drives and format raid with the existing controller
3. take one of my ide drives with the OS data on it and ghost it onto
the new scsi raid
4. copy all the data from the mirror drives to a sata mirror setup

Is there a better way to do this without building a second server? I
don't want to reinstall windows and all the apps that we run... could
this work? If it doesn't I can just put everything back how it was.

What does OT computer gurus think?

What operating system?

You mean with a new controller, I assume.

That should work. Just make sure you install the new RAID card in the
old machine (and get it working with drivers and everything) before you
ghost.

That's how I did it, except I didn't use ghost, I used a similar tool.
It was either Casper or Paragon Drive Backup.
