With AWS DMS, you can use OCI MySQL Heatwave as a source in much the same way as you do MySQL. Using OCI MySQL Heatwave as a source requires a few additional configuration changes.

For information about versions of OCI MySQL Heatwave that AWS DMS supports as a source, see [Sources for AWS DMS](CHAP_Introduction.Sources.md).
