processors replacement

Your execution plans are going to need updating. They are
developed using a combination of cpu, memory and disk
speed, so if one changes its going to effect the rest.
Its not a big job, just look up update statistics, then
watch your server fly...

They have to shut down the server to add the upgrades and all execution
plans are lost when you stop sql server anyway. And the plans are not
directly related to disk speed at all. Even CPU and memory are things that
are taken into account at run time and not necessarily at compile time. A
complex plan will always have a single and a parallel plan created the first
time it is run. At run time it is decided based on how busy the cpu's are,
memory available, etc that determine if the single threaded plan is used or
a parallel plan and how many threads generated.
