I'm sure someone will have a better way but I would expect this is going to take awhile no matter what anyone says. Assuming ESXi itself is not installed on the same array, my thought would be to: 1) get hold of a 1TB external hard drive, these can be had for $80-$100 on newegg, plug it into a PC on your network and create share on it 2) map to this share on the PC where your vsphere client is installed 3) shutdown all of your VMs and start exporting each as an OVF to the share 4) following the exports you will probably want to remove the VMs from your inventory 5) after that you may also want to remove your datastores 6) also at some point you'll have to put the host into maint mode, shutdown the host 7) remove your old drives and your old raid card, set them aside for now, if things go bad then worse-case scenario I suppose you still have everything intact install your new raid card and new drives 9) create your new array 10) boot up the host and take it out of maint mode 11) should now be able to create a new (larger) datastore on the array 12) import your OVFs from the share back over to the new datastore
