My challenge is that I need to preserve the UUID, MAC address, and any other information that is unique to the source VM.
Once I upload the VM to ESXi a customization is automatically happening assigning a new MAC address, UUID, etc., how can I avoid that from happening?
I need the VM on ESXi to be exactly the way it was on Workstation. I know that I can manually set the MAC on ESXi, but that doesn't prevent whatever other customizations are happening.
UPDATE:joeqwerty's comment about the UUID was good, however I was unable to change the MAC address to what it needed to be. On Workstation it's 00:0C:29:63:3E:BA, when I try to set a manual address in ESXi it suggests the first 6 to be 00:50:56: when I enter the Workstation address instead I receive the following error message:
Failed to start the virtual machine.Module DevicePowerOn power on failed.Could not set up 'macAddress' for ethernet0.Invalid MAC address specified. 00:0C:29:63:3E:BA is not an allowed static Ethernet address.It conflicts with VMware reserved MACs.
This is an issue with an unpatched 5.1 install and has been fixed in 5.1 U2, and 5.5, see http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2035707
UPDATE 2:Even though the above link states that this issue has been resolved in 5.5 it has not actually been resolved and the MAC address restriction still shows up until one manually edits the vmx file to disable the MAC address check as explained in the above link.

You can manually assign a MAC address (as you've stated) and you can manually specify the UUID by editing the .vmx file of the VM.
