Seamless Data Migration & Platform Modernization

How 7N led a successful transition from mainframe to Microsoft-based technology​

#

CHALLENGE

Complex core platform migration


A leading provider of digital mail and document services aimed to modernize its core platform by migrating from a costly mainframe system to a Microsoft-based technology stack.

The project initially focused on transferring a large-scale database to Microsoft SQL Server (MSSQL), but the scope expanded to include:

  • Developing and optimizing new software for the updated platform

  • Replacing legacy databases with object storage solutions


These additions increased complexity, making
effective project management crucial to mitigate risks such as data loss and service disruptions.

SOLUTION

Risk-free migration

To ensure a smooth transition, 7N provided an experienced consultant to lead the project. The consultant played a critical role in delivering:

Comprehensive planning
Developing a structured migration strategy covering data transfer, software development, and system optimization

Team leadership
Managing a multidisciplinary team to navigate technical challenges and ensure alignment with business objectives

Risk management
Implementing measures to prevent data loss and minimize downtime, ensuring a seamless transition

IMPACT

After thorough preparation, the consultant led the team to successfully

On the performance of the consultant, the client commented:

The 7N consultant has been absolutely outstanding throughout the process - and even though we have done a lot of things wrong along the way, the biggest mistake is probably that he was not on the project from the start.”
