Process and dependency mapping
Document critical workflows, reports, permissions and connected systems. Identify undocumented rules and operational workarounds with the people who use the application, including the exceptions they manage manually.
Replace legacy software with a controlled transition.
Old software often contains years of business knowledge alongside its limitations. Corvanta Systems helps South African businesses assess and replace legacy applications by mapping the workflows, data and dependencies that must survive the change. The transition is part of the solution.
UNDERSTAND THE PROBLEM
Understand what the existing system is quietly doing.
An unsupported application may still determine prices, create accounting exports or hold the only reliable history of a customer account. Rebuilding its screens alone will not preserve those functions. We examine the records, business rules and downstream dependencies before agreeing what should change and what must be retained.
What your system can include.
Validated data migration
Assess available access and exports, map records to the new structure and define reconciliation checks. Plan how duplicates, missing fields and historical documents are handled before the production move.
A phased transition plan
Define release stages, acceptance criteria, training and the responsibilities around cutover. Assess whether parallel operation and a recovery path are feasible for the systems and data involved.
FROM REQUIREMENT TO WORKFLOW
How we build and verifyMake the work traceable.
Inspect workflows, data access and dependencies.
Agree the replacement scope and migration rules.
Rehearse migration and verify business scenarios.
Carry out the agreed cutover and handover.
The workflow, permissions and acceptance checks are agreed around your operation before the build.
SCOPE THE RIGHT SYSTEM
What we need to understand.
A useful first conversation starts with the work you need to control. These details help define the scope, dependencies and rollout.
Project scoping and engagements- Existing software, hosting details and authorised access options.
- Critical reports, exports, business rules and connected systems.
- Operational windows, record-retention needs and acceptable disruption.
Practical questions.
Do we have to replace everything at once?
Not necessarily. A phased approach can separate a suitable workflow or department first. Dependencies determine whether the old and new systems can operate together without conflicting records or duplicated work.
Can all of our historical data be migrated?
That cannot be assumed before inspection. Available exports, record quality, file formats and legal retention needs affect the plan. The agreed migration should specify what moves, what is archived and how completeness is checked.
