Hi Sugandh, Serge and Lucian, Good day to you, and thank you for all your replies!
What I can conclude is that CPU is important to be exactly the same -- to allow the capabilities of live VM instance migration from one host to another. However, chassis and motherboard doesn't have to be the same -- it's normal to bring in better servers over time. Please CMIIW. Will try ordering the server now and will update again if I encounter further issues. Thanks! Cheers.
