ISE downgrade from 3.0

[allanc16]

Hello, recently we purchased a couple of the new ISE 36XX series appliances and they come with ISE3.0 from factory. We need to downgrade them to 2.4 to run some testing before going to 3.0. Is the only way to downgrade is to run process from CIMC?

Hi @allanc16 ,

 ISE doesn't support downgrades of versions, only roll back patches. This will require a: installation via bootable USB or a re-image via CIMC.

 Please take a look at: ISE Installation Guide 2.6, search for SNS Appliance Reference.

Hope this helps !!!
