I have a vSphere environment.
The vCenter is 6.5
The vCenter running on the physical server.
The vCenter OS is Windows Server 2012.
The database of vCenter and vCenter Server running on the same server.
only one vCenter Server.
I want to upgrade the vCenter to vCenter Server Appliance 6.7
and enable vCenter HA.
and have some ESXi 5.5 in the environment.
Before upgrade vCenter need to upgrade ESXi to 6.X.
I want to install VUM to vCenter 6.5.
Using VUM upgrade ESXi to 6.X
Then upgrade vCenter to 6.7.
What should I do?
External PSC deployment in not recommended with 6.7, visit External Platform Services Controller, A Thing of the Past - VMware vSphere Blog and What's New in vCenter Server 6.7 Update 1 - VMware vSphere Blog for more information.
vCenter 6.7 doesn't support esxi below 6.0, so first upgrade the 5.5's to 6.X, depending on the number of hosts you can either deploy VUM on a VM or you can perform the upgrade manually. Once all the hosts have been upgraded to vCenter 6.7 supported version, you can use the VCSA migration tool to move away from the Windows based deployment.

I'm thinking:
Before upgrade,the vCenter server is all in one.
After upgrade, the PSC and the vCenter don't on the same VM.
External PSC deployment in not recommended with 6.7, visit External Platform Services Controller, A Thing of the Past - VMware vSphere Blog and What's New in vCenter Server 6.7 Update 1 - VMware vSphere Blog for more information.
What HA mode should be used in the vCenter 6.7?
This?
