The "way" is not the same...... its a Appliance.
The VCSA(vCenter Server Appliance) Installer offer a migration from from your old VCS 6.0 on windows to the VCSA 6.7. It takes all configuration, identity which mean IP,FQHN, certificates and passwords to the new installation. VCSA comes with inbuild vPostgreSQL Database.
At the end of the migration the windows server will shutdown.
