Thanks for your input. I think it works better for me to skip the fresh installs if it's not required when switching from AMD to Intel CPUs. This is because my Oracle Homes in the current servers are on EMC LUNS as well and can be easily moved over.

May be I will add a step to relink the Oracle Homes in the new server before starting up the databases.

Glad to see you got it! :)

For your purposes, AMD = Intel. A fresh install may not be necessary, but as long as you have the time, it should be fine, as the linking will catch differences in OS libraries, if there are any. Make sure that you have the same Oracle options installed! Use the installer on each server to compare, either side-by-side or output to a file for comparison.

My favorite step!
