Data Migration Best Practice - Convert DDL Automatically
The first step to a successful migration is converting the table structures, which is called the Data Definition Language (DDL). You originally had to create tables on the source system, and now you must convert those tables to a completely different proprietary system with a different way of creating tables.
The great news is that my team has already done that for you. A best practice is to take a database you want to move from the source system and convert the DDL with our automatic DDL converter. The DDL converter converts between any two source and target systems extremely effectively. If you have thousands of tables, receiving the tables in converted form will only take a few minutes.
You can then execute the table creation on the new system and create the tables in minutes. You probably won't get any errors, but you can easily modify the table creation statements if you do.
Now that you have the table's DDL created for the new system, this is the perfect time to check the data types on the new tables and make any global changes that might better fit your data.
