- End-to-End Data Center Migration & Infrastructure Modernization
Overview
1LINK, Pakistan’s premier payment service provider, operates as the backbone of the nation’s interbank transactions, powering digital banking, bill payments, and payment gateways for over 50 million end users. Faced with the critical challenge of upgrading its infrastructure without service disruption, 1LINK entrusted JBS to design and execute a seamless migration to a next-generation parallel data center environment.
With JBS’s expertise, over 250+ critical devices and cabling systems were migrated in a fully live environment with 0 seconds downtime. Both primary and disaster recovery (DR) sites remained fully operational, and the project was successfully completed one week ahead of the client’s deadline.
Challenges
Zero-downtime requirement in a live environment
The migration had to occur while 1LINK’s services remained fully live, where even seconds of outage could disrupt 50M+ daily transactions.
Migration of 250+ critical devices & cables
The project involved shifting hundreds of interconnected devices and cabling systems, where a single misstep could cascade into service-wide failures.
Nationwide trust at risk
As the backbone of Pakistan’s digital payments, 1LINK could not afford any reputational or financial damage caused by downtime, failed transactions, or loss of customer confidence.
Simultaneous primary & disaster recovery (DR) operations
Both the primary data center and DR site needed to remain active and synchronized throughout the migration to maintain uninterrupted continuity.
Key benefits of the solution
- 0 seconds downtime during live migration.
- 250+ critical devices successfully migrated.
- 50M+ end users unaffected throughout the process.
- Project completed 1 week ahead of client deadline.
- Strengthened disaster recovery and infrastructure resilience.
The solution provided by JBS
JBS designed and deployed a parallel data center environment, allowing critical systems to be migrated seamlessly without interrupting live operations. Every device and connection was carefully mapped, tested, and transitioned under continuous monitoring. With expert coordination, JBS ensured both primary and DR sites remained fully live, maintaining 100% service availability.
The migration was executed with precision, finishing ahead of schedule while strengthening disaster recovery, operational resilience, and scalability for future growth.
How it solved the challenges
Ensuring zero-downtime in a live environment
JBS deployed a parallel data center setup that allowed systems to be migrated in phases while keeping 1LINK’s services fully operational. Continuous monitoring and fallback redundancies guaranteed 0 seconds of downtime throughout the migration.
Structured migration of 250+ critical devices & cables
Every device and cable was meticulously mapped, validated, and tested prior to migration. Using a step-by-step transition plan, JBS ensured seamless relocation of 250+ critical assets without errors or data loss.
Maintaining simultaneous primary & DR operations
Both the primary and DR sites were kept live and synchronized during the migration. This dual-site continuity ensured transactional integrity and uninterrupted service across the nationwide network.
Protecting nationwide trust and business continuity
With executive oversight and round-the-clock expert teams, JBS implemented strict risk mitigation protocols. This preserved 1LINK’s reputation as Pakistan’s trusted digital backbone and delivered the project ahead of the client’s deadline.
Conclusion
Through meticulous planning and execution, JBS enabled 1LINK to modernize its infrastructure without service disruption which is a rare achievement in data center migration. The project delivered zero downtime, improved resiliency, and enhanced scalability, reinforcing JBS’s position as a trusted technology partner for mission-critical digital infrastructure.
