Enhancing Network Security: EOL Router Migration for a Financial Giant
Cloud Tech Services (CTS) successfully completed a router refresh project for a prominent global financial services provider. The project involved replacing outdated Cisco legacy routers with advanced Cisco ISR 4000 series routers within their banking data center. The upgrade resulted in a 45% increase in network throughput, reduced maintenance costs, and significantly strengthened overall performance, security, and scalability. By utilizing a structured migration approach, CTS was able to reduce downtime by 30%, ensuring business continuity and effectively addressing critical performance bottlenecks and security risks in the client’s infrastructure
Challenges Faced by the Customer
The client faced several significant challenges due to their legacy Cisco 881, 1900, 2800, and 2900 series routers reaching their End of Life (EOL). The urgent need for an upgrade to the Cisco ISR 4000 series was critical to ensure operational efficiency and security in banking services. The primary challenges included:
- Infrastructure Bottlenecks: The aging routers resulted in a 35% decrease in data throughput, severely compromising the efficiency of banking operations.
- Security Vulnerabilities: Outdated hardware heightened exposure to security threats, with a reported 25% increase in potential vulnerabilities, leaving the system susceptible to attacks.
- Scalability Constraints: The existing network infrastructure lacked the capability to support future business growth, limiting flexibility and responsiveness to market demands.
- Downtime Risk: Minimizing downtime during the router migration was crucial, as any interruptions could significantly impact critical banking services, with a threshold for acceptable downtime set at less than 2%.
- Continuous Data Flow: Ensuring uninterrupted services for banking end-customers during the large-scale migration presented a substantial operational challenge, requiring meticulous planning and execution.
Solutions Provided by CTS
CTS implemented a migration strategy involving site surveys, configuration backups, and the deployment of Cisco ISR 4000 routers. The process included meticulous change management and post-migration testing to ensure functionality and scalability. This solution improved network performance, and security, and minimized downtime.
Step by Step: The Migration Journey Unveiled
- Site Survey & Network Discovery: Conducted a comprehensive survey across primary, backup, and disaster recovery sites to identify and document routers for replacement and assess the overall network architecture.
- Backup and Configuration:Implemented backups of existing router configurations to safeguard against data loss while pre-configuring the new Cisco ISR 4000 series routers according to the documented network design.
- Site Preparation:Prepared the client’s data centers by shipping the new equipment in advance and ensuring readiness for installation, facilitating a seamless migration.
- Change Management: Developed a detailed migration schedule to minimize disruption. Change tickets were raised for stakeholder awareness, and a pre-migration call aligned all engineers on the deployment process.
- Rack and Stack: CTS engineers performed the physical installation of the routers, ensuring proper placement, cabling, and connections to the existing infrastructure.
- Migration Execution: Collaborated closely with the client’s team to execute the migration with minimal service interruptions, effectively swapping out old routers for new ones and transferring configurations.
- Post-Migration Testing:Conducted rigorous testing post-migration to verify the performance and stability of the new routers, ensuring full functionality and operational integrity.
