It then uses a SQL command script to install a sample schema and data onto the RDS Oracle DB instance that you then migrate to Amazon Redshift. This walkthrough uses a custom AWS CloudFormation template to create RDS DB instances for Oracle and Amazon Redshift. An AnalyticDB for PostgreSQL instance is created. To enable remote connections we’ll need to make a few tweaks to the nf file using the following. Perform postmigration activities such as creating additional indexes, enabling foreign keys, and making the necessary changes in the application to point to the new database. In order for Airflow to communicate with PostgreSQL, we’ll need to change this setting. The command and behavior are the same as when migration from a PostgreSQL database source, see Postgres to Postgres. It is focused on the migration of procedures, functions, and. This post covers the key functions and considerations while performing code conversion from Greenplum to Amazon Redshift. Your converted schema is suitable for an Amazon Relational Database Service (Amazon RDS) MySQL, MariaDB, Oracle, SQL Server, PostgreSQL DB, an Amazon. You can convert relational OLTP schema, or data warehouse schema.

Although AWS DMS is capable of creating objects in the target as part of the load, it follows a minimalistic approach to efficiently migrate the data so that it doesn’t copy the entire schema structure from source to target. Even though both Greenplum and Amazon Redshift use the open-source PostgreSQL database engine, migration still requires a lot of planning and manual intervention. You can use the AWS Schema Conversion Tool (AWS SCT) to convert your existing database schema from one database engine to another. Identify and implement solutions to the issues reported by AWS SCT.ĭisable foreign keys or any other constraints that might impact the AWS DMS data load.ĪWS DMS loads the data from source to target using the Full Load approach. AWS SCT performs the necessary code conversion for objects like procedures and views. Generate the schema scripts and apply them on the target before performing the data load by using AWS DMS. Run the conversion report for Oracle to Amazon Redshift to identify the issues, limitations, and actions required for the schema conversion.
