Server downgrade with Identical storage could cause performance degrade too.
I have seen case, when we upgrade from 880 2900, storage not changing, and
a simple full table scan time reduced to half. It could due to just server
bus faster, CPU speed is same for 880 and 2900 I think, 2900 was dual core,
but my full scan job is not using parallel at all.
You are doing the downgrade actually.
