We recommend that you use the following approach for the initial synchronization: In this case, data can be loaded into one side through data migration and then synced to the other side through the initial synchronization.
For example, you might have to migrate data before your go-live. The initial synchronization lets you copy existing data from one app to another bidirectionally, and there are several considerations when you run it. You can skip the initial synchronization if you don't have to sync data between the two environments. Before you start dual-write on a table, you can run an initial synchronization to handle existing data on both sides: finance and operations apps and customer engagement apps.
