VMWARE ESXI 5.0 Datastore add

I currently have an ESXI 5.0 install running on a single 500 gig SATA harddrive.

It has 3 Servers and 5 Windows 7 workstations.

I am going to add a RAID 5.

I want to install everything on the RAID and use the 500 GIG Drive as an ISO repository.

If I setup the RAID as the primary boot device and install ESXI 5.0 and then connect the 500 gig drive as a datastore should I be able to just move the VMs from the initial DS to the new DS on the RAID??

Or is there a better way to do this??

Certainly what you have proposed is do-able, or you could install ESXi 5.0 to a USB or SD card.

Here is the VMware KB on installing 5.0 on USB/SD:

Otherwise, when you re-install your ESXi 5.0 installation to your RAID 5 array, ensure this is the primary BOOT Device in the BIOS.

Install ESXi 5.0 from the ESXi 5.0 installer cdrom, it will detect an existing VMFS datastore (your original 500GB SATA disk), make sure you select preserve, and it WILL NOT overwrite and destroy the VMs, but always ensure you have good valid backups.

After installation, the new datastore (RAID5), will have a datastore name of datastore (x), and then follow my EE Article to Cut and Paste, the VMs from datastore (SATA) to new datastore RAID 5.

HOW TO: Clone or Copy a virtual machine in VMware vSphere Hypervisor ESX/ESXi 4.x or ESXi 5.0

there is an alternative, which is much faster, and that is to logon to the console or SSH (using Putty) to the server, and use the copy (cp command) to copy the files across datastores, this will complete a datastore to datastore copy on the server, rather than a copy from the server to client, and back again to datastore.
