An 8x8 Contact CenterSecondary administrator can assume a single role at a given time. However, that role can be changed by the Primary administrator in the 8x8 Configuration Manager at any time. Assigning a new role to an administrator removes them from the previous role.
To change roles for an administrator:
From the Configuration Menu, open Security.
Go to the Roles tab.
From the roles list, select a role.
Click Edit, or double-click to open the role details.
Go to the Assignment tab.
From the administrators list, find an administrator and assign to the role.

Note:
You can assign multiple administrators to a role, but assign only one role per administrator. Assigning a new role to an administrator removes them from the previous role.
