Need help with migrating External Dataflows in workspace

HI, I am Migrating Power BI contents from one tenant to another tenant- Need help with External dataflows. When I am migrating the workspace, which has dataset linked to the the external dataflows, I am not able to copy it as its only referenced to the Datasets. When I copy the Workspace its not reflected. How I can reflect the same lineage in the New the workspace copied to another New tenant. Any resource help will be very helpful.
