- - - - Pointing to DNS name of on-prem database server
      - Example of engine
        
        Can be CSV file in S3, MicrosoftSQL on Azure also can
    - - point to the RDS in AWS
  - - - **Full LOB mode – In full LOB mode AWS DMS migrates all LOBs from source to target regardless of size. In this configuration, AWS DMS has no information about the maximum size of LOBs to expect. Thus, LOBs are migrated one at a time, piece by piece. Full LOB mode can be quite slow.
        Limited LOB mode – In limited LOB mode, you set a maximum size LOB that AWS DMS should accept. Doing so allows AWS DMS to pre-allocate memory and load the LOB data in bulk. LOBs that exceed the maximum LOB size are truncated and a warning is issued to the log file. In limited LOB mode, you get significant performance gains over full LOB mode. We recommend that you use limited LOB mode whenever possible.**
  - - - Foreign keys: During the full load process, AWS DMS does not load tables in any particular order, so it might load the child table data before parent table data. As a result, foreign key constraints might be violated if they are enabled. You should disable foreign keys on the Aurora MySQL target database. You can enable the foreign keys on the target after the migration is complete.
- - - - Use Schema convertion tool.(software download from AWS_
        
        convert to supported format by destination DB engine
        
        objects that cannot be automatically converted are clearly marked so that they can be manually converted to complete the migration.
