Temp_license

[#1]

Hi Team,

I need to use a temp_license for my Infoblox's lab.

When I tried to do it i receive this message, see below

This action will generate a temporary 60-day NIOS (Model IB-V825) license.
Are you sure you want to do this? (y or n): y
NIOS (Model IB-825) license already exists - ignoring.

The license has been expirated. I need to use another one to show it to the customer 

but it is not possible.

In which way I can do it ?

How to remove the licenses that has been existed ?

Many thanks in advanced .
