3. Design the migration policy
A Microsoft Entra ID migration policy allows you to configure the attribute mappings, conflict resolution for properties only (overwrite or skip), and other options for Microsoft Entra ID migration. Refer to for details.
Note the following:
- Migration policies apply only to full migration jobs.
- Post-migration jobs are not controlled by the policy.
- Conflict resolution settings (overwrite and skip) affect only user and group property fields (such as DisplayName, Department, etc.).
- By default, all types of data (roles, licenses, managers, sponsors, and group memberships) will be merged into the destination. This means Fly will preserve existing values in the destination and add new entries from the source without removing or overwriting any data.
