Hi, I have spent some time testing our vSphere6 upgrade approach. We have 2 sites, linked mode vCenters, integrated SSO.
The recommended approach is to move to an external PSC on both sites for this setup. In a test environment, I have tried adding an external SSO first,upgrading this to an external PSC, pointing the existing vCenter to it then upgrading vCenter.
I'm not having any success with the vCenter part of this, and I wouldn't be 100% confident in such an infrastructure.
So the question is what are the pro's and con's of starting with a fresh vCenter 6 install and moving our ESXi hosts and VM's into it as opposed to the upgrade approach? I understand we will lose historical performance data for a start.
As always thanks in advance for your thoughts and experiences folks.
Steve
