Upgrade Steps

Procedure

  1. Copy the IF02 package content to the Airflow server, as described in Files to Deploy.
  2. Set the missing Variables and review the configuration files, as described in Run Variable Sync.
  3. Trigger airflow_variable_sync_26.1_IF02.

    The sync deletes the following Variables:

    • PARALLEL_TASK_RUNS
    • CDM_BRIDGE_AGGREGATE_360_LOAD_TYPE
    • CDM_BRIDGE_AGGREGATE_360_SCHEDULE
    • SCHEDULE_LDZ__ANP__MASTER_DAG
    • The per-entity snapshot schedule Variables

    The sync also renames the four master DAG schedule Variables.

  4. For Oracle or SQL Server, trigger ddl_execution_26.1_IF02, as described in the corresponding IF02 DDL execution section. For Snowflake, trigger the DAG only after you obtain the IF02 scripts and supported ordered steps and configure the step list, as described in Snowflake DDL Execution Order.
  5. For SQL Server, after the DDL DAG completes, have a DBA run Step7_post_deployment_script_sqlserver_26.1.IF02.sql, as described in SQL Server DDL Execution Order.
  6. Trigger 26.1_IF02_cleanup_dag to remove the obsolete DAG files, as described in Cleanup DAG.
  7. Confirm that the Airflow UI shows no import errors, and then run cdm_grandmaster_dag, as described in Running Pipelines.
