Advanced Database & Application Migration (ADAM) allows you to evaluate the compatibility, specifications, and migration risks of destination databases. This helps you further understand the feasibility of migrating databases to the cloud and the transformation workload.

Databases are evaluated from the following dimensions: compatibility, transformation, specifications, and risks.
- Compatibility: indicates the compatibility between the source and destination databases. A higher degree of compatibility indicates that fewer SQL statements and objects that need to be transformed.
- Transformation: indicates the number of focus areas of the destination database transformation. Database objects transformed by ADAM do not need to be modified. The focus areas of application transformation are obtained by analyzing SQL statements collected from the database during preliminary evaluation. To analyze the specific focus areas of application transformation, you can use the ADAM application evaluation feature.
- Specifications: indicates the required specifications of the destination database calculated by ADAM based on collected data. The evaluation of the specifications is subject to the data collection environment. Purchase databases based on your business requirements.
- Risks: indicates the existing risks of the source database and risks that may be generated when the database is migrated. This dimension provides you with warnings about database migration and transformation.
Evaluation details include compatibility analysis of database objects, SQL compatibility analysis, focus areas of object transformation, destination database specifications, conversions of Oracle PL/SQL to Java, and migration risks.
(1) Object compatibility analysis
(2) SQL compatibility analysis
ADAM evaluates the compatibility of SQL statements based on SQL statements executed and recorded in the database. You determine whether a specific SQL statement was issued by your business on your own or by using the ADAM application evaluation feature.
(3) Destination database specifications
(4) Migration risks
Migration risks include risks from source and destination databases. Risks from the source database may occur when you execute SQL statements that consume high CPU and use large memory in the source database, such as SQL statements of the TOP CPU and TOP Buffer types. Risks from the destination database may occur when you transform database schemas or execute SQL statements in the destination database. You must focus on migration risks to avoid performance differences caused by heterogeneous database migration.
(5) Focus areas
The Focus Areas page lists the focus areas of database transformation. You can transform your database objects based on these focus areas. You can also apply to use the ADAM database transformation feature to transform database objects. Some objects may need to be manually modified.
ADAM not only shows information about database evaluation, but also allows you to download evaluation reports. You can click Download Reports to obtain all ADAM database evaluation reports.
