Actually, I think the opposite is true. HPC clusters are usually 
walled-off computing environments, where *most* of the software being 
run on them is developed in-house or otherwise compiled from 
source-code. (I work in academia, where just about 100% of apps used are 
open-source).

Large cluster upgrades are usually "forklift" upgrades, where a new 
cluster usually means a completely new, separate computing environment 
from the previous cluster.

I think these factors make HPC clusters an *easier* place to change 
course than other computing environments.
