Abstract
Certain example embodiments relate to data migration. During setup, migration reference and change log tables are created. The former includes instructions for implementing changes to accommodate the migration. A custom migration procedure is generated to process these instructions. Triggers are created to automatically record, in the change log table, information about data-related actions performed on tables structured using the source schema. During backup, the triggers are activated, and the migration procedure is run to conform a restored version of the data in the tables structured using the source schema to the target schema. During migration, data modifications made to the tables structured using the source schema during the backup stage are replicated in the tables structured using the target schema, by processing the information about the data-related actions recorded in the change log table using the migration procedure, while the triggers also replay further data-related actions encountered during the migration.
