Architecture · Migration
Modernise without stopping the business.
Replace what’s old, & don’t break what’s already working.
Telecom modernisation isn’t a clean-room architecture exercise. The live business still has to bill, activate customers, reconcile month-end, and answer the support call while the stack changes underneath it. TAUSPACE helps clients understand the current state, define the target architecture, and sequence the migration with operational risk in view.
The buyer question
What can we change first without breaking what still works?
Legacy stacks survive because they carry revenue. They may be expensive, brittle, slow, and poorly documented, but they still hold customer data, billing logic, product exceptions, partner processes, and month-end routines.
The migration plan has to respect that reality. The right move is rarely to replace everything at once. It is to understand the domains, pick the first value point, integrate where needed, run in parallel where risk demands it, and decommission only when the new operating pattern is proven.
What we do
Architecture that the operating model can actually carry.
Current-state assessment
Map systems, data flows, integrations, ownership, operational pain, risk, and undocumented dependency.
Target architecture
Define the future-state BSS/OSS, integration, data, and operating architecture.
Enterprise architecture
Connect technology architecture to service, customer, product, partner, and revenue outcomes.
Migration sequencing
Define which domains move first, which coexist, which integrate, and which should wait.
Coexistence design
Plan how old and new systems work together while revenue, support, and operations continue.
Integration strategy
Define how ERP, OSS, NOC, partner, network, and customer systems connect.
Cutover criteria
Make the go/no-go decision measurable before launch pressure starts compressing judgment.
Service delivery alignment
Make sure the delivery model, development lifecycle, portfolio governance, and operational support model can sustain the architecture.
