AWS and ISE and upgrades

[charliey_2000]

I am trying to see if I could get some feedback about running ISE in AWS.   Saw the known limitations in AWS but the line below was not clear to me. Does this mean you can not patch or upgrade the ISE in AWS?  So you would have to stand up new servers and restore each time?

Cisco ISE upgrade workflow is not available in Cisco ISE on AWS. Only fresh installs are supported. However, you can carry out backup and restore of configuration data. When you restore the data in a Cisco ISE AWS instance, the data is upgraded to the Cisco ISE Release 3.1 version.

The ISE upgrade workflow does not apply to patches; only upgrades to new major software versions (ISE 3.1 -> 3.2, for example). To perform these future upgrades for ISE in AWS, you will need to use the Backup/Restore method described in the ISE 3.1 Upgrade Journey rather than a direct upgrade.

Patches would be applied using the same method as on-prem ISE clusters.
