Hi Theruck,

About a month and a half ago I was in a similar situation. I had a Compaq ML370 with one 18GB drive for the OS and two mirrored 36GB drives for data. In my case I needed to configure a mirrored set of 36's for the OS and four 36's RAID 5 for the data.

 I used Symantec/PowerQuest V2i Protector Small Business Edition to create a set of disk images (I think that you could also use Symantec/Norton Ghost but, someone with more experience with that product would be more help) I also ran a complete tape backup (you can never over emphasize the importance of solid backups). My final form of backup was the original 18GB and two 36GB drives.

Since in both cases you will be changing your RAID configuration, your steps will be similar;
Create your Disk Images and Tape Backups and verify them.
Make sure that you have your array controller driver (should be on your Compaq/HP SmartStart CDs)
Down your server, make the physical drive changes.
Start your system, go in to your array controller configuration
Remove and Create the appropriate arrays
Using the V2i Protector cd, boot the server and finally restore your images to your new array(s).

I use V2i as a part of my daily backups because it is such a good "on the fly" backup and restore tool.

Good luck on your project, I hope this helps.
