type Migration1_0To2_0 ¶
type Migration1_0To2_0 struct{}
Migration1_0To2_0 migrates export data from version 1.0 to 2.0.
This is an example migration that demonstrates the migration pattern. In a real scenario, this would transform data structures, add new fields, or rename existing fields as needed for the new version.
Changes in 2.0:
- Add metadata field with migration information
- Add migrated_from field to track migration history
Thread Safety:
Safe to call concurrently.
Example:
migration := &Migration1_0To2_0{}
migrated, err := migration.Migrate(oldData)
if err != nil {
log.Printf("Migration failed: %v", err)
}
