Upgrade vCenter 5.5 U2 with Multiple vCenters to vSphere 6.0

[BriansVblog]

I'm in the process of planning out a vSphere 5.5 U2 upgrade to vSphere 6.0.  This particular environment is currently architected as follows:

Looking at KB 2108548 (http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=210854...), it appears this setup is being deprecated in vSphere 6.0.  As such, I believe my vSphere Upgrade process looks like the following:

1. Deploy a new separate external vCenter 5.5 U3 SSO (only) Windows server or VCSA.
2. Re-point/re-register all four vCenter Server's Inventory Service, vCenter Service and Web Client to the new SSO server as described in KB 2033620 (http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=203362...).
3. Uninstall SSO from the original vCenter server it was hosted on.
4. Upgrade the new external SSO server to PSC (6.0).
5. Upgrade the four Windows vCenter servers to vCenter 6.0.

Am I missing anything or are there any gotchas I should be aware of?  Thanks in advance for your help.

I would install the SSO (PSC) and the vCenter each on another Server.

Yeah the procedure looks fine, in addition, you can go for PSC behind HA mode to have redundancy as running multiple VCs with one single sso can have larger impact in case of issue with SSO. here are few articles for the same :-
