David_1 on "Admin Role Network No to Super Admin"

Hello Friends,

Using WP version 3.6.1.
Fresh instal and beginning to develop.

My question is: Is it possible to raise an Admin to Super Admin Role without setting up a Multisite?

I have access to the Cpanel - PHP - My Admin.

The reason I am asking is for our use I Multisite is going to be overkill as we are only creating one WP website. There are four Administrators. We really need to convert one to Super Admin.

Any advice would be greatly appreciated.
