Re: 820 upgrade from an S20 -- MIDRANGE-L

Points to remember. the 820 is not a migration tower, the old S20 is the
migration tower. It is the S20 minus CPU and Memory, with HSL circuitry added.
It's sole purpose is to allow the S20 peripherals to attach to the 820, which is
a OCI bus. the 820 will contain all the memory. I do not belive that the S20
memory can be reused in this scenario. Also, the new drives will be on a higher
speed adapters than the old drives.
