I am migrating several VM's with SAN storage (RDM) from Intel chipset to AMD chipset. They will all retain their configurations and be on the same network. The best method I can see right now is to export each VM to an appliance and then import them onto the new servers. I wanted to see if anyone had any other ideas are what to look out for with this method.
If the intel hosts and AMD hosts are controlled by Virtual Center, you can just migrate them. The VM must be powered off. When you power it on on the AMD hosts, you should n't need to do anything.

Can't see any problem. Add AMD ESXes to VI and cold migrate VMs usual way. That's all.
VMs do not care about chipsets at all.

While this is mostly true, it is not strictly true.
Windows VMs will generally be fine, but Solaris x86 and some Linux variants (SuSE, for example), make install-time decisions based on the actual CPU that they see.
Contrary to common belief, the CPU is actually exposed to the virtual machine -- the virtual motherboard effectively has a 'hole' in it where the physical CPU shows through. This is for performance reasons -- the CPU is not emulated, rather, most instructions are passed through w/o modification.
