Re: What are best practices for upgrading host hardware? (4core -> 6core)

Hello AP,

Thanks for your replies.  I've got more info for you.

My versioning is as follows:

WMware Infrastructure Client v2.5.0 build 341446

VMware VirtualCenter v2.5.0 build 341446

ESXi servers are 3.5.0 build 391406

Today I tried a different way, by attempting to connect to the production hosts using my test vcenter server, and I got a message stating that the host is already being managed by another vcenter IP, and that only one vcenter server may manage the host.  It then asks if I want to disconnect the host from the original management server.  I tell it no as I do not want to interfere with production.

I would very much like to add this 3rd server to my production cluster so I can move VMs to it and decommission one of the older hosts.  I seem to keep hitting a wall. 

Suggestions?

Thanks!
