Yes, we also tried that. That fixed issues with SSL certificates, IIS admin and SMTP services, but it created new problems for us. For example, we have two SQl servers with always on enabled. I was not able to failover to the converted one. The cluster did not work, despite the same host name, same Ip address and the machineGUID. We were concerned it might break something else. We are using Veeam to backup then convert. That seems to be working so far, the machineGUID remains the same as original. Hope that helps.
