This change introduces a sample (`migration_session_db`) demonstrating how to load a session database created with an older version of ADK (e.g., 1.15.0) and make it compatible with the current version. It includes a script (`db_migration.sh`) to alter the SQLite schema automatically. to_event is updated to handle potential discrepancies in pickled `EventActions` by using `model_copy` to ensure compatibility with the latest `EventActions` model definition. Related to #3272 #3197, Closes #3197 #3272 Co-authored-by: Dongyu Jia <dongyuj@google.com> PiperOrigin-RevId: 826524368
