Hi All,

I am having an issue around the hardware compatibility. 

We are using version 3.X ISE with 1 PAN and MNT node. 

On VM: ESXi 6.7 and later (version 14)

On Host: ESXi7.0 U2 and later (version 19). 

Can I go ahead and upgrade to match host?

Appreciate your assistances.

Cisco documented the compatibility in the 3.0 Installation Guide here:

https://www.cisco.com/c/en/us/td/docs/security/ise/3-0/install_guide/b_ise_InstallationGuide30/b_ise_InstallationGuide30_chapter_2.html

(search for "VMware Virtual Machine Requirements for Cisco ISE").

Later versions of the document (3.1+) seem to have removed this particular reference.

I always update the VM compatibility if the version change only results in new features like more RAM support, more CPU support, and loads of things that have no bearing on ISE.  Never had a problem. The requirements for ISE (Redhat Linux) are quite simple and somewhat flexible. The ISE VM doesn't need more RAM or CPU of course, and it also doesn't complain about it either. You can take a look at this link from VMWare (broadcom will soon break this website too) to see a feature comparison table of the versions .

Here's a screenshot for posterity

Yes - you should upgrade the VM to match host.

Hi @Marvin Rhoads,

How would I know if my ISE is compatible - apologies as I am not seeing any good details on the doco. 
Appreciate if you can help share some doco if there is any.

What exact version of ISE?  You have no PSN?  Only a PAN and MnT?  What exactly are you using ISE for?
