I have downloaded patch 11 and found it to be 2.39 GB in size. I am wondering if anyone has already made this change and how long did the patch 11 take to complete the installation.</P><P>I have a two-node deployment with a hardware appliance model 3515 and a virtual appliance with the same specifications as the hardware appliance 3515.</P><P>I need to schedule a maintenance window for this.</P><P>&nbsp;</P> Fri, 17 Jan 2020 16:50:59 GMT https://community.cisco.com/t5/network-access-control/ise-2-4-patch-8-to-patch-11-time-required/m-p/4013592#M454431 RSundstrom 2020-01-17T16:50:59Z https://community.cisco.com/t5/network-access-control/ise-2-4-patch-8-to-patch-11-time-required/m-p/4013613#M454433 I would plan for about an hour per node, but it's usually about 40 minutes. <BR /><BR />20-25 to install, 15-20 to restart the node after.
