Upgrade 6.0 (Separate DB , PSC , VC) to 6.7U2 (VCSA all in one)

Hello guys,

Im planning to upgrade my vcenter environment from 6.0.0 (Build 3634793) to latest 6.7u2a.

currently i have 3 servers :

1.DB - for SQL running on windows 2012r2

2.PSC - Platform Services Controller running on windows 2012r2

3.VC - vCenter running on windows 2012r2

I want to remove this mess and create one VMware vCenter Server Appliance on Server 2016..(maybe later i'll create another one for HA.)

whats is the proper way to Upgrade my environment?

of course that later ill update my ESXi hosts one by one to 6.7u2 also..

Thanks for help
