Migration of ESXi Host to new physical Hardware

We have two ESXi Hosts running on HP Proliant G5 Servers; 2 CPU's (8 cores) and 32GB ram each.  Each server has a single 8gb HBA (Qlogics QLE2560).

We have purchased two new HP Proliant G8 Servers; 2 CPU's (16 cores) and 160GB of ram each.  Each server has the same single 8gb HBA (Qlogics QLE2560)

We imaged the flash drives for the running VMWare Hosts.  

We shut down all virtual machines and both Hosts.

We installed the duplicate flash drives into the first host.  The server booted and recognized the HBA's.  The Hypervisor began to load and got 99% complete.  I did get a failure on the HBA driver but the Hypervisor continued to load and then crashed and a dump (purple screen, white letters),

In the dump, one of the messages instructed us to "run vicfg -rescan -a after boot.  Not sure what this means or how to do it, since the I never get to a command prompt.  Not sure if this is tied to the HBA either.

Again, we are using the exact same part number in the hosts that were running.

We ultimately, turned off the new G8 Host machines and rolled back to using the G5 hosts.  

Not sure where to go next.

Sorry I didn't get the who dump picture.

Personally, because the hardware is different (CPUs, PCI Bus, Memory), I would use the latest OEM HP ESXi 5.1 installation, or whichever VMware vSphere version you require, especially as moving the OS installation from one server to another has failed.

It should not take long from documentation, to re-configure the host.

This is the supported and safest method of deploying ESXi.

Are the firmware's for the HBAs the same? (I would still do a fresh installation).

Hello,

vicfg -rescan -a  - Rescans all the Storage adapters,

so if the Host is crashing at a PSOD after this. seems to be a firmware or driver related to the storage.

Try and upgrade your HBA with latest firmware and drivers.
