Upgrading Acrobat Standard software to Pro after assigning new Pro license.

I work in a corporate environment and we have hundreds of licenses, distibuted through the Adobe Admin Console.  Users cannot purchase their own licenses, we assign them from a pool purchased by IT.

A user who had an Acrobat Standard license required the features of Pro, so we assigned her a new license.

What precisely needs to be done to upgrade the Standard software to Pro?

I know that the end user can upgrade Reader to Standard/Pro without needing an Admin password by signing in, restarting, and selecting Install Premium Features from the Help menu.  Does it have a similar menu item for going from Standard to Pro?
