Refresh Sandbox MSD from Production

Lenovo needs the ability to refresh a “sandbox” MSD environment from a “production” MSD environment and have the native sync continue to work in Sandbox Marketo (without having to migrate to a net new Marketo instance).  Lenovo refreshes the “sandbox” MSD environment from “production” MSD twice annually via the process documented here:  https://docs.microsoft.com/en-us/power-platform/admin/copy-environment.  It is our understanding that “refreshing” an MSD instance like this results in having to provision a net new Marketo instance and having to do a migration from the “old” Marketo Sandbox instance to the new one - and this process is too time consuming to complete twice a year.  We understand that this functionality is available for Marketo’s native sync with Salesforce but not with Dynamics.
