SOTI > Intune Contacts

Hi All

A wee question about migrating devices from SOTI > Intune with regards to user's native Contact app contacts.

These are Android Enterprise Fully Managed  / COBO device with no personal Google accounts on them so prior to any migration, how can we ensure that the user's native Contact app contacts reappear in Intune?

I know that App Config policies will do a sync from Outlook > native Contacts app, so I'm kinda looking for the reverse here!!!

Any suggestions are very welcome.
