• CutoverCutover is the planned sequence of steps that switches a business from an old system or process to a new one: freezing changes, final data migration, reconciliations, technical switch and first checks. A cutover plan lists every task with its owner, timing and rollback point.
• ETL (extract, transform, load)ETL is the process of extracting data from source systems, transforming it (cleaning, mapping, joining, aggregating) and loading it into a target such as a data warehouse. ELT is the variant where raw data is loaded first and transformed inside the target platform.
• Legacy decommissioningLegacy decommissioning is the controlled shutdown of an old system once its functions and data have moved elsewhere. It covers archiving records for retention, removing interfaces and access, ending licences and evidencing that nothing still depends on the system.
