I am running ISE 2.4, on prim Admin I have installed patch 6, 9 but on sec Admin installed only Patch 9. because my secondary Admin was build months later so I did not install patch 6 on the same.
Is there any problem??
Solved! Go to Solution.
Patch 9 or any recent patches will usually include all the fixes on the previous patches.
So technically patch 9 already covers 1-8.
I haven't done like that so far where I have to derigester the node with different number of patches.
The document on Cisco shows vague info as well, unless it just really says same version and it doesn't care about the patch.
"• Ensure that the Primary PAN and the standalone node that you are about to register as a secondary node
are running the same version of Cisco ISE." - (https://www.cisco.com/c/en/us/td/docs/security/ise/2-2/admin_guide/b_ise_admin_guide_22/b_ise_admin_guide_22_chapter_010.pdf)
I still think that it would work as again, you have the same version 2.x and same recent patch.
