ISE Licensing Migration

Hi ISE Team,

Customer currently has 5000 Mobility licenses installed on their ISE Administration Node.
They are in the process of obtaining 20,000 ISE Base licenses to replace the Mobility licenses with. They do not have these Base licenses yet, because the sales process for these has not completed yet.
Because Mobility licenses cannot be installed at the same time as ISE Base licenses, once the customer has obtained the Base licenses, they will take a maintenance window to remove the Mobility licenses, and then upload the Base licenses.

The question is: What happens to the ISE cluster in the time where the Mobility licenses have been removed, and before the Base licenses are uploaded? Does this cause an outage to all ISE clients and features, or is there a certain time period they have before the cluster will stop functioning? The plan is to upload the Base licenses very quickly after the Mobility ones have been removed, but we want to understand if *any* outage is caused during this process.

Thanks for the help, and please reach out to me if you have questions about what is being asked.

David, even without license, the nodes will continue to function for end users without impact. However, you will not have access to the GUI once you log off until you install a new license. If you don't log off then as soon as you delete the Mobility License you have an opportunity to install the base license right away. Once you move from Mobility to Base license you lose some features including profiling, BYOD/MDM, and Posture, which you will need to re-login to get the UI refreshed to reflect that. Often you may need to delete the cache on the browser to get the proper UI after the license change.
