Go to the Database Migration Service (DMS) in the AWS Management Console:

Within DMS, to get started, we can first create a new Replication Instance

On the next screen, you can use these values to configure and create a new Replication Instance
| Setting | Value |
|---|---|
| Name | DMS-Lab |
| Description | DMS-Lab |
| Instance class | dms.t2.medium |
| Engine version | 3.1.4 |
| Allocated storage (GB) | 50 |
| VPC | (choose your current VPC - should only be 1 available) |
| Multi AZ | no |
| Publicly accessible | no |

It takes a few mins to create the Replication Instance, and for it to be in Active state
