We have a customer that is planning an upgrade from v1.2 to v2.1. Their current Guest portal flow uses custom portal pages uploaded into ISE, so I have 2 questions.
- When they perform the upgrade from 1.2 -> 1.3 -> 2.1, will the custom portal pages be removed?
YES, if they must upgrade would recommend 1.2 > 1.4 (latest patch) then to 2.1)
- If the pages are removed, how can we upload them again to provide the same portal flow as current? I remember Craig mentioning a workaround for this (I think using the Client Provisioning Resources) but I have not been able to track down any documentation on it.
There is no upload support of HTML flows per say. you can upload to file remediation but its not meant for special customized flows
It would probably be ideal to wait for the feature in 2.2, but the customer has concerns about the EOL of 1.2 and wants to perform the upgrade ASAP.
2.2 has custom portal files supported. 1.4, 2.1 can use the file remediation location. https://supportforums.cisco.com/discussion/12344731/ise-13-portal-customization-background-image
You should be looking into deploying 2.1 in the lab and doing a fresh install and having the custom rebuild using the new concept. It sounds like its complex as well. I really only recommend using the portal upgrade as a stop gap. They might even look into the ISE portal builder for support if they don't have the expertise.
Perhaps a parallel system on ISE 2.1.
