# Step 5: Create an Instance Profile


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

 **To create a subnet group** 

1. Sign in to the AWS Management Console and open the AWS DMS console at [https://console.aws.amazon.com/dms/v2/](https://console.aws.amazon.com/dms/v2/).

1. Choose your AWS Region.

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

1. For **Name**, enter `PrivateSubnetGroup`.

1. For **Description**, enter `A group of private subnets`.

1. For **VPC**, choose `sc-vpc`. You created this VPC in [Step 1](schema-conversion-sql-server-aurora-postgresql-step-1.md).

1. For **Add subnets**, choose two private subnet IDs. You noted these private subnet IDs in [Step 1](schema-conversion-sql-server-aurora-postgresql-step-1.md).

1. Choose **Create subnet group**.

Before you create your migration project in DMS Schema Conversion, you set up an instance profile. An instance profile specifies network and security settings for DMS Schema Conversion.

 **To create an instance profile** 

1. Sign in to the AWS Management Console and open the AWS DMS console at [https://console.aws.amazon.com/dms/v2/](https://console.aws.amazon.com/dms/v2/).

1. Choose your AWS Region.

1. In the navigation pane, choose **Instance profiles**, and then choose **Create instance profile**.

1. For **Name**, enter a unique name for your instance profile. For example, enter `sc-instance`.

1. For **Virtual private cloud (VPC)**, choose `sc-vpc`. You created this VPC in [Step 1](schema-conversion-sql-server-aurora-postgresql-step-1.md).

1. For **Subnet group**, choose the `PrivateSubnetGroup` subnet group that you created before.

1. For **S3 bucket** under **Schema conversion settings - optional**, choose an Amazon S3 bucket that you created in [Step 1](schema-conversion-sql-server-aurora-postgresql-step-1.md).

1. For ** IAM role**, choose the AWS Identity and Access Management (IAM) role that grants access to Amazon S3. You created this role in [Step 1](schema-conversion-sql-server-aurora-postgresql-step-1.md).

1. Choose **Create instance profile**.

Use this instance profile when you create your migration project in [Step 7](schema-conversion-sql-server-aurora-postgresql-step-7.md).
