Issue with upgrading ISE from Version 2.1.0.474to 2.3.0.298

Hi everyone

I am trying to Upgrade a Cisco ISE PSN and getting this error:

********

STEP 3: Validating data before upgrade...

%warning: Cannot upgrade this node as new PAP has patch(es) installed on it, please remove the patch(es) and try again.
********

I am running ISE version 2.1.0.474 Patch version 5.

I have deployment setup and just upgrade my Secundery ISE Server node with out any problem with the same version and Patch(es).

Does it mean that I need to uninstall all the Patch(es) from the ISE PSN before to upgrade to the version 2.3.0.298?

Patches are cumulative and normally you should be able to upgrade from 2.1 patch 5 to 2.3. However there is a bug in the 2.3 upgrade process in that it fails to properly ascertain the readiness when one or more of the target nodes was patched non-sequentially. 

You should open a TAC case and they will be able to help you with a work around.
