# Prerequisties for migrating from SAP AWS to Amazon Aurora MySQL


The following prerequisites are required to complete this walkthrough:
+ Familiarity with Amazon Relational Database Service (Amazon RDS), the applicable database technologies, and SQL.
+ Understand the supported features and limitations of AWS Database Migration Service (AWS DMS). For more information, see [What Is Database Migration Service?](https://docs.aws.amazon.com/dms/latest/userguide/Welcome.html).
+ Accomplish the prerequisites required for using an SAP ASE database as a source for AWS DMS. For more information, see [Prerequisites for using an SAP ASE database as a source](https://docs.aws.amazon.com/dms/latest/userguide/CHAP_Source.SAP.html#CHAP_Source.SAP.Prerequisites).
+ Understand the limitations on using SAP ASE as a source and MySQL as a target for AWS DMS. For more information, see [Limitations on using SAP ASE as a source](https://docs.aws.amazon.com/dms/latest/userguide/CHAP_Source.SAP.html#CHAP_Source.SAP.Limitations) and [Limitations on using a MySQL-compatible database as a target](https://docs.aws.amazon.com/dms/latest/userguide/CHAP_Target.MySQL.html#CHAP_Target.MySQL.Limitations).
+ Accomplish the prerequisites required for using a MySQL-compatible database as a target for AWS DMS. For more information, see [Using a MySQL-compatible database as a target](https://docs.aws.amazon.com/dms/latest/userguide/CHAP_Target.MySQL.html).
+ Set up the network for AWS DMS replication. This includes configuring VPC, private subnets, availability zone, and adding connections on the source firewall if it exists. For more information, see [Setting up a network for a replication instance](https://docs.aws.amazon.com/dms/latest/userguide/CHAP_ReplicationInstance.VPC.html).
+ Download and install AWS Schema Conversion Tool (AWS SCT) with the required SAP ASE and MySQL JDBC drivers. For more information, see [Installing, verifying, and updating the Schema Conversion Tool](https://docs.aws.amazon.com/SchemaConversionTool/latest/userguide/CHAP_Installing.html).
+ Know the recommendations on the most efficient way to use AWS DMS. For more information, see [Best practices](https://docs.aws.amazon.com/dms/latest/userguide/CHAP_BestPractices.html).
