Following are the details you need to provide while creating the sync group:-

  1. Provide the meaningful name to the sync group name.
  2. Sync Metadata Database – Microsoft recommends creating a New database for this property. But for the sake of the demo, I am using the existing database.
  3. Automatic Sync – If you select On, then enter a number and select Seconds, Minutes, Hours, or Days in the Sync Frequency section. The first sync begins after the selected interval period elapses from the time the configuration is saved.
  4. Conflict Resolution – It has two options: Hub win and Member win. Hub win means when conflicts occur, data in the hub database overwrite conflicting data in the member database. Member win means when conflicts occur, data in the member database overwrite conflicting data in the hub database.
  5. Private Link – This option is in preview mode as of now and will be managed by Microsoft. Once you click on Ok, It will create the Sync group as shown below.
