Striim Migration Service for Google Cloud Documentation

Perform the initial load

When the source and target databases are the same type (for example, PostgreSQL to Cloud SQL for PostgreSQL), the source and target tables are identical, and you use the databases' native tools to copy the source tables to the target, this step is unnecessary.

When you have tested the initial load and streaming integration applications, and know that the initial load can complete in the amount of time available, perform the initial load. See the Oracle to Google Cloud PostgreSQL Migration Guide for an example.
