Data centre migration

Client : Financial institution

The customer, whose IT services are provided by a large multinational outsourcer, needed to close one data center and move it to another due to a change of supplier.

Due to the nature of its business and the confidentiality of its data, security, integrity and availability issues were at the heart of the customer’s concerns.

In addition to the migration, the customer’s equipment had to be upgraded (modernization and automation) and the outsourcer had to set up the infrastructure to accommodate the end customer’s data.

Because the virtualization technologies used were new, some activities had to be performed outside of business hours so as not to affect the systems in production.


  • Migration of critical and confidential information
  • Very short lead times to complete the migration without impact on users
  • Several different teams needing to work together between ESI, the outsourcer and the end customer
  • Some of the systems to be migrated were not in production

Our Contribution

This critical project for the end customer required close collaboration between the different stakeholders involved. ESI’s delivery team contributed several areas of expertise: virtualization, storage and backup. In order to meet deadlines and share information effectively, ESI organized several joint planning sessions beforehand to ensure that all aspects related to this migration were taken into account and to better anticipate problems. This preparation allowed the teams to adopt alternative solutions in the event of problems.
