The best way is backup and restore.

If can't, you can try this way, but high risk and long time,

1) One by one replace the hard drive; take out one 60GB drive, then put one 300GB, wait it rebuild complete, then 2nd and 3rd same step, wait rebuild then replace
2) After all 3 disks rebuild, run RAID manager, expand volume in existing RAID group.
3) Run diskpart in command prompt to expand the volume on Windows partition.

FIRST: REGARDLESS OF THE METHOD MAKE SURE YOU HAVE A CLEAN FULL BACKUP.

While I am a fan of the Backup, Blowout, Rebuild, Restore method usually there is no problem with the method mentioned above. The only thing to consider is this:

-----------------------------------------------------------------
Diskpart does NOT extend system and boot partitions is only supports extension of data partitions.

> What are the risks involved in your three step solution?
If you extend the system or boot partition using Dispart.exe the file system may not be extended, causing your computer to hang.

To accomplish this you must use a 3rd party utility like Partition Magic or Server Magic.
-----------------------------------------------------------------

BUT if the volume / partition you are trying to extend is not the system or boot partition you SHOULD be okay. Again I cannot stress enough the need to have that backup!

Good luck!

You may probably take the image of the system using Norton ghost or acronis True image

Replace the disks and create the new RAID Volume. While you remove the disks, Name the disks as 1,2,3 as per slots because it may be required if you want to revert back to old disks.

Restore the image

I could never get Ghost to work with RAID controllers. True Image however worked quite well. Even the free demo of the Workstation version did th trick.

my question is if i get the system image of the system with ACRONIS true image...doesn't matter if the replacing Hard drives are diffrent from the one the image is taken from?

and also, since i am installing these new hard drives, don't i have to format the drives first before restoring the image?
i am new to this...any help is very much appreciated.
thanks...

I have used Ghost for this in the past, but you will need to create your own boot disk with the PERC RAID drivers.  Dell's website has these dos drivers.  Ghost will see the array as just one drive, so once you have ghost able to see the array it is a cake walk.

Hope this helps.
