hardware RAID1 and new HDD's

[edge]

At the moment I have 2 HDD's of 120GB in my server.
They are set in RAID1 (with use of a 3Ware RAID card).

I have 2 new HDD's of 250GB.

Basicly what I would like to do is move the server over from the two 120GB HDD's to the new 250GB HDD's without reinstalling the OS (& rest) again.

As I have set the two 120GB HDD's in RAID1 mode I was thinking of 1st changing one of the 120GB drives to the 250GB one, and let the RAID1 'copy' the system back to the new 250GB drive, and than change the other 120GB one to the new 250GB.

Anyone here who knows of it can be done this way?
If not... Is there an other way of moving a good working system without reinstalling to bigger HDD's?

As your new hdd's are bigger than the old ones, you'll have to modify the master script of the image to reflect the bigger hdd's before you restore the image to the new hdd's (otherwise you'll only use 120GB of 250...).
