ECA disaster recovery options

A customer is asking to verify a disaster recovery option for an ECA.
They have a tool in place that would clone an ECA to another datacenter VM environment in the event of production ECA or datacenter outage. The clone would use the same hostname, but would possibly have a different IP address.
The question: If the EDAs were connected over a Direct connection to the ECA using the hostnames, would the Clone ECA reconnect to the EDAs and retain all the customizations (dashboards, device groups, and access permissions)?
Thank you
