Upgrading vCenter Appliance 6.0 Experience
Wasn't was I aware after doing some research to find out VCSA in version 6.0 does not have admin portal to do the upgrade. Instead I need to upload the update file from here (you got to login to your account).
I followed this guide from this user.
Apparently after upgrade form baseline 6.0, the admin portal for the appliance is been returned. Glad that is an one time experience.
Why was the admin 5480 been left out in the first place?
