Code & language
COBOL, RPG and related application logic.
Mainframe Modernization
Mainframe Modernization with Operational Continuity
Tambition approaches modernization through its z/OS and enterprise-systems consulting foundation. Work begins with the existing application, data and operating context. AI may support research, evidence organization and analysis; migration choices, testing, change approval and fallback remain under human control.
Legacy Modernization Challenges
Modernization spans code, data, platform mechanisms and operations.
Middleware & OS
Runtime, interfaces and platform mechanisms.
Data & batch
VSAM/DB2 data, batch jobs and scheduling.
Integration & operations
Interfaces, testing, cutover and ongoing operational change.
HSG Modernization Capability
Tambition provides Canadian service coverage for Hi Sun Global (HK).
Tambition Technologies Group Inc. serves as a designated Canadian service provider for Hi Sun Global (HK). Tambition brings local mainframe and enterprise-systems experience into HSG modernization engagements in Canada, while HSG contributes financial-services modernization, core-system implementation and integration capability.
Engagement scope, responsibilities and delivery commitments remain project-specific. No exclusivity, guaranteed outcome or blanket migration recommendation is implied.
Modernization Workstreams
Modernize in controlled stages across code, data, platform and operations.
Application / code conversionCOBOL / RPG and application logic.
Data migrationData structures and movement.
Batch & middlewareSchedules, runtime and interfaces.
Simulation / testingComparison and integration testing.
CutoverApproval, transition and validation.
OperationsRun-state checks and fallback readiness.
Platform & Rehost Paths
Choose migration paths based on workload, risk and operating constraints.
AS/400 offloading
Assess AS/400 offload paths while preserving interfaces, batch processing, data integrity and service continuity.
x86 / Linux / Open Platform
Evaluate x86, Linux and open-platform rehosting based on workload fit, dependencies, testing and operational risk.
Open COBOL / HBOX context
Evaluate Open COBOL and HBOX-based rehosting patterns against application, data, integration and operational requirements.
Historical Case Context 01 — Macao Banking
Cross-platform migration and operational continuity.
A historical banking modernization case involved a legacy core, interfaces and integration, middleware, testing, cutover and operational continuity. The institution remains anonymous, and unverified claims such as zero disruption, faster transactions, savings or scalability are not presented.
Historical Case Context 02 — Southeast Asia Consumer Loan / AS400 / RPG
Offload, RPG conversion, batch scope and service continuity.
A historical consumer-loan modernization case involved AS/400 offloading, RPG conversion, batch workloads and an open-platform target while protecting service continuity. The organization remains anonymous; no current relationship or performance outcome is asserted.
Historical Case Context 03 — Chinese City Commercial Bank / x86 / Open COBOL / HBOX
Phased rehost and platform-function context.
A historical city-commercial-bank case involved x86 and open COBOL rehosting, HBOX-related platform functions and phased modernization. The institution remains anonymous, and unverified branch-count, cost, speed-to-market and performance claims are not presented.
Delivery Boundaries & Contact
Assessment first. Controlled change, validation and fallback throughout.
Modernization engagement is framed as a human-controlled sequence rather than a promise of zero disruption or guaranteed business outcome.
