Creating a subnet group for an Amazon DMS migration project

Before you create an instance profile, configure a subnet group for your instance profile.

To create a subnet group

  1. Sign in to the Amazon Web Services Management Console and open the Amazon DMS console at https://console.aws.amazon.com/dms/v2/.

  2. In the navigation pane, choose Subnet groups, and then choose Create subnet group.

  3. For Name, enter a unique name of your subnet group.

  4. For Description, enter a brief description of your subnet group.

  5. For VPC, choose a VPC that has at least one subnet in at least two Availability Zones.

  6. For Add subnets, choose subnets to include in the subnet group. You must choose subnets in at least two Availability Zones.

    Choose subnets that provide network connectivity between your replication instance and your source and target databases. The subnet type (public or private) does not by itself determine connectivity to Amazon RDS or on-premises databases; make sure the subnets you choose can reach your databases.

  7. Choose Create subnet group.
