Changing the CUCM from IP Address to FQDN will affect the Cisco VCS Expressway C&E Integration

[ccg-collab1]

Hi Everyone,

We are planning to change the CUCM from IP Address to FQDN, question changing to FQDN will impact the Cisco VCS Expressway C & E integration to CUCM? 

Thank you

I don't think it will, but you should update VCS to use the FQDN also.
