I have a bunch of servers that we are going to swap from Core i3's to Xeon E3's. We did a test swap and RHEL booted without issue. We are getting more cores so it isn't an issue where the current applications are going to have fewer resources.
Here's my question: is there anything I need to worry about in Ubuntu, RHEL or CentOS? I know swapping boot drives from one chassis to the next never works easy because of changing NIC MAC addresses. What about CPUs? I wouldn't think there's anything to worry about but wanted to see if anyone here found an issue.
