DATADrone4 for SQL Serverâ„¢ - Schema Migration

Schema Migration is a three-step process. After a proper configuration and activation, DATADrone4 will connect to the database instance being migrated from (the source). It will extract the complete schema for each instance (all databases within each instance) that the user wants migrated.

These schemas will include the table description, primary and foreign key data, procedures, and any triggers associated with each database (all data objects) contained within the instances to be migrated. After the schemas have been extracted they will be run through a series of proprietary grammar parsers, which will generate and store data objects for generating the like target schema.

Step two of Schema Migration involves analyzing the intermediate data objects to determine the order that the tables need to be migrated in order to ensure that data integrity is assured and maintained.

The final step involves parsing the intermediate data migration schema files, generating and executing system specific SQL for table and index creation. As each table is successfully created, all of its data will be moved and loaded. The last phase of this step is the recreation of constraints, procedures, and triggers.
