I have a usecase to migrate 300+ EC2 VMs to GCE and plan to use the Migrate to Virtual Machines GCP Service ver 5.x (formerly called Velostrata). Looking at its Architecture I see that it uses the Cloud Migration API which is a Google API / private Google access.
I am looking to use Cross Cloud Interconnect to setup a private high speed connectivity between AWS and GCP instead of using the public internet. The documentation for Migrate to Virtual Machines does not mention any support for Cross Cloud Interconnect. My question is how do i configure private Google Access for Cross Cloud Interconnect to to be able to connect to the Cloud Migration API privately similar to Private Google access for On-Premises hosts mentioned in this link?
