I have requested for an upgrade of existing server (starter-SEN-xxxxxxxx) to 25 users. However, I received as a new product with different SEN number. And, I wasn't able to apply the license key to the existing License key.
The error message as below:
The license could not be installed.
This license is not for the selected product. Please make sure that the license is for the selected product and contact Support if the issue continues.
