Caution
Replication overwrites any data in the target table. You do not receive any notification that the data in the target database will be overwritten, even if the target table's design does not match the source table. Verify that the tables you want to replicate either do not exist in the target database or do not contain data that you need. Be especially cautious when replicating entire schemas to prevent overwriting data in the target database.
Similarly, changes to a replicated table in the target database are overwritten each time you replicate the table. When performing scheduled replications, only grant read access to replicated tables in the target database. Limiting these tables to read-only access will help prevent confusion if a user makes changes to a replicated table.
