Cisco ISE - replacing Portal certificate

We have a two node ISE deployment running 2.2. I’ve looked at the Cisco documentation for replacing certificates, and it leaves a lot to be desired. We currently use a internal certificate and this means our guest portal doesn’t work properly because clients without our internal root certificate cannot trust it, so need to use a publicly signed certificate.

Has anyone done this before, and if so what SANs did you use, and what was the process for replacing the certificates on the ISE nodes?
