Upgrade host processor from Intel Silver to Intel Gold and add more RAM?
-
I was finally able to get my account reset and I'm back with what is probably a stupid question, but here it goes...
I have 3 hosts with Intel Silver 4210 processors (10c/20t), had to go this low due to funding. I may need more CPU for a specific function so I'm looking at upgrading to Intel Gold 6252 (24c/48t) and probably double my ram to 256gb in each host. These are both Scalable v2 CPUs and should fit in the power budget of my servers (but subject to verification).
I'm guessing that since these processors are the same family, that I should be able to just shut the host down, swap processor and add ram, power it back up and repeat two more times. Is this correct? Or are my Windows hosts going to be a problem? There shouldn't be any VM/software/OS locked to processor ID or anything like that, so I think I'd be OK.
If I needed, I can probably migrate everything away from one host, remove that host from the pool, install hardware, install XCP-NG again, add it to the pool, migrate back and repeat. Only hard part would be move the pool master for the last step in the rotation.

Going for worse to better CPU won't be a problem at all
All features won't be unlocked until all hosts of the pool will be on the new ones. Then, you'll need to reboot (via XO/XAPI) your VMs to be re-init and use the latest CPU features that you didn't get previously. -
Thank you, that's what I thought and why I was willing to buy the lower end CPU in order to get the project through. At the time going for the larger Gold would have doubled the cost of each server.
