Essex County Council Data Center Migration Testing

Essex County Council Data Center Migration Testing

Essex County Council embarked on a program of work to migrate from their existing data center solution to a new hosted data center. The program was time constrained, due to contractually binding migration dates, and Essex County Council needed to engage an independent and objective testing capability to de-risk the migration from the old data center to the new one. QualiTest was asked to work alongside the new hosted data center supplier, working for and on behalf of Essex County Council, to provide independent and objective Quality Assurance, Quality Governance and Testing of the migration program.

Client Overview

Essex County Council is a county council that governs the non-metropolitan county of Essex in England, serving a population of over a million people.

Business Needs and Objectives

In 2009, Essex County Council embarked on a program of work to migrate from their existing data center solution to a new hosted data center. The program was time constrained, due to contractually binding migration dates, and Essex County Council needed to engage an independent and objective testing capability to de-risk the migration from the old data center to the new one. QualiTest was asked to work alongside the new hosted data center supplier, working for and on behalf of Essex County Council, to provide independent and objective Quality Assurance, Quality Governance and Testing of the migration program.

The QualiTest Solution

Having undertaken a large number of migration and infrastructure projects across a wide range of customers in the previous decade, the proposed solution leveraged QualiTest’s domain knowledge, skills and experience in this area.

Drawing on QualiTest’s previous experience with large telecoms providers, government departments and utility companies, QualiTest demonstrated to Essex County Council that they had previously undertaken business critical migrations of many applications, including CRM and billing applications, and the associated databases. These projects involved large scale data migration and, coupled with QualiTest’s experience of testing in complex infrastructure projects, QualiTest were able to assure Essex County Council that they would be able plan, analyze, and design an effective and efficient approach to the data centre migration testing. In addition, QualiTest were also well placed to execute and report on this approach so that Essex County Council was provided with informed risk-based decision making points throughout the program lifecycle. At the heart of the solution were QualiTest’s professionally trained and highly skilled test consultants. QualiTest proposed that Essex County Council engage two of their most technically capable Test Team Leaders, to interface with both the business users and the server and network experts. Export, Transform and Load (ETL) experience and knowledge and experience of leading Data Migration Tools were pivotal to the solution.

In addition, QualiTest provided an Operational Acceptance Test Manager, who also coordinated configuration
management activities, environments, defect tracking and defect management. The Operational Acceptance
Test Manager and Test Team Leaders were supported by two experienced Test Analysts.

Working closely with the Essex County Council data migration program team, alongside the new hosted data center supplier, QualiTest delivered a clear, effective and efficient risk-based approach and plan for the quality assurance, quality governance and testing of the Essex County Council data migration program. At each step of the lifecycle QualiTest provided key decision making information to Essex County Council about their readiness to progress to the next stage and any risks that would be transferred to the next stage. This has resulted in the successful and seamless migration of the six highest priority applications from the old Primary Data Center to the new infrastructure plus the “lift and shift” migration of more than forty applications from the old Secondary Data Center. This success has led to the extension and re-engagement of QualiTest’s Testing Services for the remaining migration of the forty plus applications which were subject to the “lift and shift” approach.
