Step 4: Analyze discovery data - AWS Database Migration Service

Step 4: Analyze discovery data

AWS DMS Studio is in preview release for AWS Database Migration Service and is subject to change.

Next, you analyze your local database information, and get recommendations about how to migrate your data to AWS.

To analyze your local database information and get migration recommendations

  1. In the AWS DMS console, choose Inventory in the navigation pane.

  2. On the Inventory page, choose the Databases tab. Choose Analyze inventories.

  3. After analysis completes, choose the Schemas tab to see information and recommendations.

    You use the analysis information to determine which databases should be migrated to AWS. To determine good candidates for migration, check the following:

    • The Complexity result shows how many lines of code are in the database. Databases with a Complexity result of Complex are databases with a large code base and are likely candidates for migration. This is because these databases are probably essential to your infrastructure.

    • Schemas with a high Similarity score are usually duplicates of other schemas, such as duplicate databases used in staging. Databases with a high Similarity score aren't good candidates for migration. This is because these databases are probably redundant copies of your main databases.
