Synchronize with another replica set member in a database
Synchronization is the process of updating two members of a replica set by exchanging all updated records and objects in each member. Two replica set members are synchronized when the changes in each have been applied to the other.
Open the replica set member you want to synchronize.
On the Tools menu, point to Replication, and then click Synchronize Now. (If a Synchronizer on the Internet manages any replica set member, you will see that the managed replica appears in the Directly with Replica drop-down list box as http://ServerName, where ServerName is the name of the Internet Server.
Enter the path and file name of the replica set member you want to synchronize with the current database.
If your database is the Design Master and you want to make the other replica the Design Master, select the Make 'Filename' The Design Master check box. (This option is unavailable if either of the replicas to be synchronized is a partial replica.)
Click OK.
When asked whether you want to close and reopen the database, click Yes. (If you click No, you might not see all of the changes.)
