Final answer:
DMS supports both homogenous and heterogenous migrations.
Step-by-step explanation:
The type of migrations that DMS (Database Migration Service) supports is both homogenous and heterogenous migrations.
Homogenous migrations refer to migrations between the same database management systems, while heterogenous migrations refer to migrations between different database management systems.
For example, DMS can support migrating a database from an on-premises Oracle database to an Amazon RDS for Oracle instance, which is a homogenous migration. It can also support migrating a database from an on-premises Microsoft SQL Server to an Amazon Aurora PostgreSQL, which is a heterogenous migration.
