ISE 2.4 patch 8 to patch 11 - Time Required?

[RSundstrom]

Hello,

I am at ISE 2.4 patch 8 and am going to install patch 11 in the near future. 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.

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.

I need to schedule a maintenance window for this.

I would plan for about an hour per node, but it's usually about 40 minutes.

20-25 to install, 15-20 to restart the node after.

Damien, thank you for the super quick reply. I will set aside one hour per node.
