ISE Patching 3.3 patch 4 to 8

[maysobano37]

Just a referemce point for folks who will be performing this particular patching

6 Node deployment consist of 4 VMs and 2 3650s

İt took 3 hours to complete due to chassis taking a long time to initialize application server

It’s been 2 days and no issues, something must have been wrong with Patch 4, after upgrading to 8. Authentication latency dropped to sub 50ms. İt was awfully high with patch 4

Thanks for sharing this reference. I have seen similar behavior when moving from ISE 3.3 Patch 4 to Patch 8. Patch 4 sometimes caused high authentication latency, which is resolved in Patch 8.
