Make sure you select premium tier as online migration is not supported in basic tier. provide inputs like resource group name and Migration service name. To create, search for Database Migration Service in all resources and click create. Now I will create Database migration service in Azure and create a migration project. Since my schema is simple, i dont need to do that however when you migrate make sure you remove indexes and triggers and enable them after the migration. REVOKE ALL ON SCHEMA public FROM rdsadmin ĭMS needs that we remove indexes and triggers as DMS does not support them due to parallelism. Next, I will remove RDS specific statements in the script like the one mentioned below else the script will fail. I will also have to add the IP of my Laptop to firewall of Azure Database for PostgreSQL. I will take a dump from AWS RDS with schema_only option and execute the sql script on the destination in Azure Database for PostgreSQL.įirst I will create the destination database in azure and then execute the script taken in the above steps using psql as I took a plain sql dump. Next step is to create the same schema in the destination as DMS does not create the schema in PostgreSQL online Migration. Once the data is synced we will simulate a cutover to the Azure DB.īelow screenshot shows the AWS RDS for PostgreSQL provisioned in its own VPC. I have a simple insert script which is inserting data into this table in intervals and we will see how to migrate this data using online migration. I have a sample schema running in AWS RDS which has a single table called Users in a database userdb which we need to migrate. AWS RDS for PostgreSQL deployed in a VPC.I have following deployed in my AWS account and Azure Subscription. Change logical_replication to 1 in AWS RDS and run the Migration Activity till Databases are sync'ed.Restore the script on target Azure db for PostgreSQL.Backup schema from AWS RDS and remove RDS specific code and indexes/triggers from the backup script.with this, I believe we can deploy a EC2 instance and use that for DMS however nothing confirmed as of now) AWS RDS connectivity to Azure Database Migration Service using a public IP exposed from DMS and added this IP to AWS RDS security group which is also publicly accessible.So lets start.īelow are the broad steps that I took for this Migration We will see step by step implementation of the same. It is assumed that you have deployed an AWS RDS for PostgreSQL which is supposed to be migrated to Azure Database for PostgreSQL. The focus of this article is to learn how to use Azure Database Migration Service (DMS) for online migration of Data from AWS RDS to Azure DB for PostgreSQL. This article does not cover deploying AWS RDS or Azure Database. This article will cover a very common scenario of Migrating AWS RDS for PostgreSQL to Azure Database for PostgreSQL. Migrating AWS RDS for PostgreSQL to Azure Database for PostgreSQL using Azure Database Migration Service.
