You refer to the servers as being in a cluster - I am guessing this means they are in a failover cluster? Unfortunately the Migration Assistant does not support clustered IIS servers as a migration source at this time. I have updated the main wiki page with this detail in the FAQs server requirements: https://github.com/Azure/App-Service-Migration-Assistant/wiki.
Thank you for reporting this. We will consider enabling this type of server source in future and/or improving the error message for this case. If I've misunderstood and your are not using clustered servers please let me know and I will provide instructions for getting some additional debugging information.

You are correct my server are in a cluster environment.
