ISE 2.4 or 2.6 - 3595 or 3655

[Craig Rees]

We are migrating from 2.1 to 2.4 or 2.6 because of some bugs TAC has identified.  we have 4 3495s which do not support anything past 2.4. we need to purchase 4 new SNS appliances.  2.4 is not currently supported on the 3655.  Does Cisco recommend we purchase the older 3595 hardware and upgrade to 2.4 or purchase the newer 3655 hardware and upgrade to 2.6.

End-of-Sale and End-of-Life Announcement for the Cisco Secure Network Server (SNS) 3515 and 3595 for ISE Applications shows SNS 3595 is reaching EoS on 2019-June-15.

If you are implementing this within the month or two, I would suggest to add more memory and disk to 3495s, install VMware, and run ISE nodes as ISE VMs.

If further out, then it's good to purchase 36xx appliances with ISE 2.6 and install the latest patch, when available.
