ISE Upgrade

[fatalXerror]

Hi Experts,

I am planning to upgrade my VM ISE 1.4 distributed deployment however, I wanted to have minimal downtime as possible. What I want to do is to deploy another VM ISE 2.x distributed deployment and just copy manually the configuration from my production ISE 1.4 then during the migration, I will just point the NADs to the new VM ISE 2.x distributed deployment.

My question now is, is it possible to re-host the licenses from my VM ISE 1.4 to my new VM ISE 2.x?

Thanks

Yes, the ISE licensing is transferable. You can work through TAC to complete the procedure. It is also helpful if you can provide the original Cisco sales order number from when the licensing was purchased. This will allow a seamless issue of new medium VM licenses that would have been ordered in the past as RTU, and now get installed on the deployment. 

If the person that originally fufilled the licenses via cisco.com is available, then you can rehost the licenses yourself at http://www.cisco.com/go/license.

Last but not least, consider having the licenses rehosted in to a smart licensing account. It is the direction all Cisco products are heading, it makes ISE licensing self service for times like this easier, and you can leverage the pool of licenses in production and a lab if desired.
