Cisco ISE 3.1 VMWARE Guest Operating System

[LUCA_ITALY]

Hi to all.

We have just upgraded an ISE Deployment based on 2 nodes from 2.7 to 3.1.

We follow this beautiful doc: https://www.cisco.com/c/en/us/td/docs/security/ise/3-1/upgrade_guide/Upgrade_Journey/Cisco_ISE_3-1_Upgrade_Journey.html

In the post update update section is reported to change the VM Guest OS:

"If you are upgrading Cisco ISE nodes on virtual machines, ensure that you change the Guest OperatingSystem
to Red Hat Enterprise Linux (RHEL) 7 (64-bit) or Red Hat Enterprise Linux (RHEL) 6 (64-bit)."

In another doc: https://www.cisco.com/c/en/us/td/docs/security/ise/3-1/upgrade_guide/HTML/b_upgrade_overview_3_1.pdf it is reported that RHEL 8.2 should be used.

We follow he upgrade guide so we have RHEL 7 (64bit) selected.

Someone can confirm me that is correct?

Thank you

 - The last link (...overview) only refers to the 'inner os' that ISE3.1 is running on not  the guest os that the hypervisor uses , so you are good to go.
