THE KEY RESULT
Critical Infrastructure Relocated Without Business Interruption
Viyu planned and executed the migration on a tight timeline while maintaining business processes and avoiding impact to the organization’s service-level agreements.
01 — The Challenge
A regional financial services organization needed to relocate critical IT infrastructure from an office that was closing to a secure colocation environment.
The infrastructure included an IBM AS400 system, supporting servers, and networking equipment essential to daily operations.
The migration presented several challenges.
Mission-Critical Legacy Systems
The AS400 and supporting infrastructure required careful physical handling and reconfiguration during the move.
Limited Documentation
Legacy systems lacked comprehensive documentation and credential access, increasing the complexity and risk of the migration.
Business Continuity Requirements
Users depended on uninterrupted access to file shares, VPN connectivity, and AS400 applications for everyday operations.
Viyu needed to complete the relocation on a tight timeline while minimizing downtime and maintaining critical business services.
02 — The Viyu Solution
Viyu coordinated the complete colocation migration, managing planning, secure transport, network reconfiguration, cutover, and post-migration support.
Physical Infrastructure Relocation
Viyu relocated the IBM AS400, supporting servers, and networking equipment to the vArida datacenter.
Network Reconfiguration
All server and virtual machine IP addresses were updated for the new subnet.
Viyu then confirmed access to Hyper-V, the AS400 environment, and file shares following the move.
AS400 Management
Viyu configured an AS400 management server to support ongoing administration of the environment.
Post-Cutover Support
After the migration, Viyu assisted users and technology partners with application-specific issues, including DNS, ODBC, and AS400 adjustments.
Business Continuity Planning
Every stage of the migration was coordinated around maintaining access to critical systems and minimizing operational disruption.
03 — The Results
AS400 Online Without Issue
The IBM AS400 was successfully brought online following the relocation.
Successful Post-Cutover Backup
A full backup was completed after the migrated environment was operational.
Minimal Business Disruption
The organization transitioned to the colocation environment while maintaining continuity for critical business processes.
User Access Restored Quickly
Users regained access to file shares, VPN connectivity, and applications within expected timeframes.
Stable Colocation Environment
The organization moved critical infrastructure into a stable datacenter environment while decommissioning infrastructure at its previous office.
Application Support After Migration
Viyu continued assisting internal IT staff and technology partners with DNS, ODBC, and AS400-specific adjustments following the move.
