Migrate your loan book with a staged, parallel-run method.
The fear of moving a live loan book keeps many lenders on a system they’ve outgrown. A staged migration turns that fear into a plan — extract, validate, reconcile and run in parallel before cutover, so data loss and downtime are managed, not gambled.
Can we migrate our loan book with minimal risk?
Yes. We extract your loan book, validate and reconcile it against your current system, and run both in parallel until the numbers agree — only then do we cut over, in a planned low-activity window. A staged, parallel-run method is how a Sri Lankan MFI moves systems without gambling its data or its uptime.
How the staged migration works
Five stages, each with a checkpoint you can see. Nothing goes live on trust — the parallel-run phase proves the new system matches the old before anyone depends on it. This is the method that de-risks moving off a core system you've outgrown.
- 1
Scope & assess
We map your current loan book, chart of accounts and data quality, and agree what moves first — so the plan fits your book, not a template.
- 2
Extract & map
Your data is extracted and mapped to the new system's structure, with the rules documented so nothing is transformed silently.
- 3
Validate & reconcile
Migrated balances are reconciled against your current system. Discrepancies are found and resolved here — before they can affect a live operation.
- 4
Parallel run
Both systems process the same activity side by side, and their numbers are compared until they agree. Confidence is earned, not assumed.
- 5
Cutover & support
Cutover is planned for a low-activity window, with local support in place. The old system stays available as a reference until you're settled.
Why parallel-run is the part that removes the fear
The risk in any core banking migration is discovering a mismatch after you depend on the new system. A parallel run moves that discovery earlier: both systems process the same activity, their balances are compared, and cutover only happens once they agree. You migrate on evidence, not on hope.
It is the same principle that runs through everything we build — put the hard part behind the scenes and make the outcome something you can trust. For your officers, migration should feel like an ordinary week; for your auditors, it should leave a trail that reconciles.
Frequently asked questions
Can we migrate our loan book without losing data?
Yes. We extract your existing loan book, validate and reconcile it against your current system, and only cut over once the numbers match. A staged, parallel-run method means the old and new systems run side by side first, so discrepancies are caught before cutover rather than discovered after it.
How much downtime does migration involve?
Because the new system runs in parallel with your current one before cutover, day-to-day operations continue during preparation. Cutover itself is planned for a low-activity window, so downtime is minimised and predictable rather than open-ended.
What if the migrated numbers don't reconcile?
That is exactly what the parallel-run phase is for. Both systems process the same activity and their balances are compared until they agree. You do not cut over on trust — you cut over on a reconciliation you can see, which is what de-risks the move off a system you've outgrown.
How long does a core banking migration take?
It depends on the size and cleanliness of your loan book and how many modules you move first. A staged migration lets you start with one part, prove it, and expand — so the timeline scales to your scope rather than forcing a single high-risk cutover. We scope it with you before anything moves.
