Migrating ESXi 3.5 virtual machines to 4.0 version on the same host

I have existing ESXi 3.5 host with 3 virtual machines on it. Host runs on 4 internal SATA disks, which form RAID 10 array.
Now, I bought 2 additional 15k rpm SAS disks, which I will put into host and will form RAID 1 array. I also added 16 GB of RAM to host.

Well, my intention is to get the best of the host regarding performance, so I wish to:
- use newly inserted SAS disks in RAID 1 array as root for all my VM's
- use old SATA RAID 10 array as storage array for VM's (like 2nd partioins for DATA, for example)

So, I am looking for best plan how to migrate existing hosts to new confgiguration under the same host machine.
Should I install ESXi 4.0 fresh new on new SAS RAID1 array, and then somehow pull out existing VM's from old SATA RAID 10 array, and convert them? Is this a good idea?

Suggestion welcome!
