Avenryx SystemsUse case
Move years of history without losing the audit trail
Data migration is where projects quietly overrun. The fix is to look at the real data early, not during cutover weekend.
Outcomes
- Data quality known before commitment
- Cleansing decisions made by the business
- Validation evidence after each run
- A cutover that has been rehearsed
Use case
Where it is used
Profiling
What is actually in the old system, not what people believe.
Cleansing
Rules agreed with the business, applied consistently.
Validation
Row counts, checksums and spot-check reports.
What we deliver
- Source profiling
- Mapping and transformation rules
- Repeatable migration runs
- Validation and reconciliation reports
- Cutover rehearsal and rollback plan
Who this is for
- Teams replacing a system where historic data must come along.
- Projects where a previous migration attempt produced data nobody trusts.
Problems this solves
Source data is worse than assumed
Profiling the real export early turns migration from an unknown into a scoped task with a cleaning plan.
No agreed cut-over
A rehearsed cut-over with a freeze window, verification checklist and rollback removes go-live improvisation.
Nobody can prove the migration worked
Record counts, checksums and business-level checks — balances, open orders, stock — signed off before the old system is switched off.
How delivery runs
- 01
Observe the current process
We watch the work as it is actually done, including the workarounds, before proposing anything.
- 02
Scope the first slice
One workflow, one team, one measurable target — chosen because it carries the most manual effort.
- 03
Build and pilot
Working software in a pilot group within weeks, running alongside the current process until the numbers agree.
- 04
Roll out and switch off
Migration, training and a dated switch-off of the old route, so two processes do not run forever.
Realistic timeline
Week 1
Profiling the real export and agreeing scope of history.
Weeks 2–4
Mapping, cleaning rules and first rehearsal.
Weeks 5–6
Second rehearsal, verification checklist and cut-over.
What moves the price
Data quality
Cleaning and de-duplication is the dominant cost, not the transfer itself.
History depth
Migrating years of transactional history costs far more than opening balances; often only some of it is needed.
Number of rehearsals
Each full rehearsal costs time but removes the largest go-live risks.
Where projects go wrong
Migration verified only by record counts
Business-level reconciliation — balances, stock values, open orders — is required before sign-off.
No way back
A tested rollback and a retained read-only copy of the source system for a defined period.
FAQ
Questions buyers ask
Should we migrate everything?+
Usually not. Active records migrate; history is often better archived in a read-only view.
How long does it take?+
Profiling is days. The full cycle depends entirely on data quality, which is why we profile first.
