Key Factors of a Successful Data Migration

Achieving Success in Data Migration: Repeatability, Predictability, and Timeliness

A successful data migration hinges on excellent communication with clients, which is the core of our BIDM methodology. Additionally, we emphasize three technical factors that contribute to the success of any data migration project: Repeatability, Predictability, and Timeliness.


Our proprietary data manipulation tools and automation techniques ensure that the data migration process is both repeatable and reliable. By consistently applying:

  • Automated source and target system refreshes
  • Data extracts
  • Script execution
  • Data quality checking, tagging, and loading
  • Auditing and reporting

We can run the data migration process end-to-end as often as needed, ensuring accurate and dependable results every time. For critical systems with large data volumes, repeatable automated processes are essential.

Repeatable processes mitigate risk


To ‘guarantee’ the result of the final data migration, the main cut-over and system go-live deployment, the expected result should be known beforehand. This concept is extremely difficult to obtain, given

  • The ever-changing nature of the data
  • Unknown data quality errors introduced just prior to the final migration
  • Target system changes
  • Migration requirement changes
  • Changes in project resources

Our entire methodology at DataMC focuses on delivering a predictable outcome for businesses during the final data migration and system go-live event. Repeatability ensures that all potential scenarios are encountered and addressed before go-live.

We work towards 100% predictability

Timeliness – the Runsheet

In addition to repeatability and predictability, the timeframe of the go-live migration is also critical to the success of a data migration project. A thorough and accurate runsheet is vital, outlining:

  • The order of all tasks to be completed
  • The times taken for each task

All aspects of a data migration should be known before a go-live event is initiated. Under no circumstance should this be attempted without an accurate and comprehensive fully scheduled runsheet being developed. With a runsheet, all timeframes should be known and achievable, without it, the outcome and success of a project go-live can not be predicted in advance.

A realistic go-live timescale that can be followed and achieved is essential
