![]() max_wal_senders = - The max_wal_senders parameter sets the number of concurrent tasks that can run, recommend 10 tasks.Ĭ. Set the rds.logical_replication parameter in your DB parameter group to 1.ī. The rds_replication role grants permissions to manage logical slots and to stream data using logical slots.Ĭreate a new parameter group with the following configuration:Ī. If you use an account other than the master user account, the account must have the rds_superuser role and the rds_replication role. Use the master user name to connect to the source from Azure Database Migration Service. To create a new parameter group, follow the instructions provided by AWS in the article Working with DB Parameter Groups. Set up AWS RDS PostgreSQL for replication ![]() Provide the subnet range of the virtual network used for Azure Database Migration Service. When using a firewall appliance in front of your source database(s), you may need to add firewall rules to allow the Azure Database Migration Service to access the source database(s) for migration.Ĭreate a server-level firewall rule for the Azure Database for PostgreSQL server to allow Azure Database Migration Service access to the target databases. Open your Windows firewall to allow Azure Database Migration Service to access the source PostgreSQL server, which by default is TCP port 5432. For more detail on virtual network NSG traffic filtering, see the article Filter network traffic with network security groups.Ĭonfigure your Windows Firewall for database engine access. For more information about creating a virtual network, see the Virtual Network Documentation, and especially the quickstart articles with step-by-step details.Įnsure that your virtual network Network Security Group rules don't block the outbound port 443 of ServiceTag for ServiceBus, Storage and AzureMonitor. ![]() Refer to this section of the document for detail on how to connect to the PostgreSQL Server using pgAdmin.Ĭreate a Microsoft Azure Virtual Network for Azure Database Migration Service by using the Azure Resource Manager deployment model, which provides site-to-site connectivity to your on-premises source servers by using either ExpressRoute or VPN. For example, RDS PostgreSQL 9.6 can only migrate to Azure Database for PostgreSQL 9.6, 10, or 11, but not to Azure Database for PostgreSQL 9.5.Ĭreate an instance of Azure Database for PostgreSQL or Azure Database for PostgreSQL - Hyperscale (Citus). For more information, see the article Supported PostgreSQL Database Versions.Īlso note that the target Azure Database for PostgreSQL version must be equal to or later than the RDS PostgreSQL version. The source PostgreSQL Server version must be 9.5.11, 9.6.7, 10, or later. Prerequisitesĭownload and install PostgreSQL community edition 9.5, 9.6, or 10. ![]() This article describes how to perform an online migration from an on-premises instance of PostgreSQL to Azure Database for PostgreSQL. If the expected downtime isn't acceptable, do an online migration. We recommend that you test an offline migration to determine whether the downtime is acceptable. To limit downtime to the time it takes you to cut over to the new environment after the migration, use an online migration. ![]() In an offline migration, application downtime starts when the migration starts. In Azure Database Migration Service, you can migrate your databases offline or while they are online. ![]()
