Cisco ISE Patch

[Mateen Ahmad]

Hello,

I am running two  ISE 2.4 nodes in Prim Admin and Sec Admin and PSN enabled on both.

I have installed patch 6, and 9 on Prim Admin and only Patch 9 on Sec Admin. As my Sec Admin was build Months later than Prim Admin so I did not install patch 6 on the same.

Is there any problem???

ISE patches are cumulative so there is no need to install previous patches before installing the latest patch.

Unless you are on version 2.1, since there was an upgrade bug that required the sub patches to be identical on all nodes.

It Will not be any issues if I registered again my secondary node as we are running different patches
