The migration process will check to make sure there is sufficient disk space to complete this action beforehand. Global Administrators can log in to monitor the status of the migration during this period. After the migration completes, the Security Console backs up the pre-migration database and ...

Step 1: Configure SQL Server database for Replication or Change Data Capture In this walkthrough we create a “migrate existing data and replicate ongoing changes” DMS migration task. This type of DMS task will perform an initial copy of all existing data from source to the target, and ...
Testing: Rigorously test the migrated database for integrity, performance, and compatibility with applications. Optimization: Tune the PostgreSQL database for optimal performance based on the specific use cases. Deployment: Plan a cut-over to the new system with minimal downtime. Implement replication...
