ISE Upgrade - 2.3 - 2.4. SNS3400 -SNS3500

[avallely]

Hi my customer wants to upgrade their ISE estate from 2.3 on SNS3400 to 2.4.  The release notes advise that 2.4 is not supported on SNS3400 Series, therefore it appears as though they would need to purchase SNS3500 servers.

Is it possible to transfer the existing licenses to the new servers. If so what is the process.

Thank you.
