ISE Upgrade Time

[pagosojayson]

Hi,

We have two ISE  appliances running on 2.0.0.306 configured for distributed deployment setup.  I have a requirement to upgrade it to 2.3.  I would just like to check with you guys how much time it will take to upgrade both devices  One is running as primary for all personas(Administration, Monitoring, Policy Service) and other is running as secondary for all personas.

Here are the disk sizes:

Priamry/admin# show disks

disk repository: 9% used (1220856 of 14985796)

Internal filesystems:
/ : 18% used ( 89686464 of 549834344)
/dev/shm : 0% used ( 0 of 8099972)
/boot : 8% used ( 32577 of 481800)
/storedconfig : 2% used ( 1585 of 89231)
/tmp : 3% used ( 41776 of 1975372)
all internal filesystems have sufficient free space

Secondary/admin# show disks

disk repository: 9% used (1220664 of 14985796)

Internal filesystems:
/ : 56% used ( 95595980 of 180476204)
/dev/shm : 0% used ( 0 of 8166968)
/boot : 8% used ( 32295 of 481764)
/storedconfig : 2% used ( 1585 of 89231)
/tmp : 3% used ( 45076 of 1975372)
all internal filesystems have sufficient free space

Hi Jayson

the answer to your question is to use the URT tool (Upgrade Readiness Tool) because that will run all sorts of consistency checks on your 2.0 PAN, and then also give you a DETAILED analysis of the time taken to upgrade all nodes in the deployment.  It's a great tool.  Download it from software.cisco.com and then install it on your Secondary PAN node.  Running it there has no impact to the operation of the node.
