Loan management system migration and implementation methodology
The six-phase approach Lokta uses to move an enterprise loan book from a legacy LMS onto Lokta. Sign-off gates between phases; daily reconciliation through pilot; hypercare into BAU. This is Lokta's own plan, the one tool in the toolkit that is not vendor-neutral.
Methodology principles
Three principles drive every phase. They appear in the contract, the kickoff deck, and the daily standup.
- Sign-off gates between phases. No phase begins until the previous phase's deliverables are signed off by the steering committee. This is non-negotiable.
- Daily reconciliation in pilot. Parallel run with the existing LMS continues until accounting events tie out for five consecutive business days.
- Reversibility through pilot. Until the production go-live decision, the lender can revert to the existing LMS without data loss.
This page assumes the decision to move has been taken. If it has not, the migration assessment works through whether it is warranted, and can end with a recommendation to stay where you are.
Discovery & fitment
Assess the lender's current Loan Management System (LMS), product catalogue, and operational reality. Map RFP requirements to platform capabilities, with explicit gaps identified.
Deliverables
- Current-state assessment of the existing LMS
- Product catalogue review with composability mapping
- Loan-lifecycle mapping against Lokta's lifecycle states
- Integrations inventory with priority sequencing
- Data-model mapping for migration planning
- Security and deployment topology decision
- RFP-requirement coverage matrix
Solution design
Lock the target architecture before configuration begins. The design phase ends with a sign-off package that everyone (lender, integrator, Lokta) references for the rest of the engagement.
Deliverables
- Target architecture document (deployment, network, identity)
- Tenant model with isolation boundaries
- IAM model: roles, permission groups, org-unit hierarchy
- Loan product configuration design
- Accounting-event design with GL mapping
- API and integration design with versioning policy
- Reporting model and dashboard specification
- Migration plan with validation gates
Configuration & integration
Configure products, wire integrations, and define operational workflows. End-state: the platform is ready for migration data to flow in.
Deliverables
- Loan products configured per the design
- Charges, fees, and allocation rules configured
- DPD bands and asset-classification thresholds set
- Maker-checker workflows defined per policy boundary
- User roles, permission groups, and OrgUnits provisioned
- Integration adapters built and tested in non-prod
- Notification flows wired from audit events
- AI servicing use cases configured with RBAC scoping
Migration & validation
Move the loan book into Lokta and prove the numbers. Migration ends only when validation gates pass: outstanding balances reconcile, schedules match, charges round correctly, accounting events tie out.
Deliverables
- Customer / party migration with deduplication
- Loan account migration with lifecycle state mapping
- Repayment schedule migration with interest validation
- Transaction history migration with allocation replay
- Outstanding-balance validation against source system
- Charges and waivers validation per product
- DPD validation across delinquent accounts
- Accounting reconciliation per GL line
- User acceptance testing with sign-off
Pilot & parallel run
Run a controlled production pilot with parallel servicing on the existing LMS. Daily reconciliation; explicit go / no-go gates before the wider rollout.
Deliverables
- Pilot portfolio scope (branch, region, or product slice)
- Operational training for servicing, collections, and operations teams
- Parallel run alongside the existing LMS
- Daily reconciliation report covering payments, balances, accounting events
- Exception register with RCA and resolution
- Go / no-go criteria signed off by the steering committee
Production rollout
Cutover, hypercare, business-as-usual. The wider book moves to Lokta; the existing LMS is decommissioned according to the lender's schedule.
Deliverables
- Cutover plan executed with named owner per workstream
- Hypercare period (typically 30-60 days) with daily standup
- Support governance: escalation matrix, on-call rotation
- SLA activation with monitoring dashboards live
- Enhancement backlog kicked off
- Quarterly business review cadence agreed
Typical timeline
The ranges below are typical for a single product line; multi-product or multi-partner engagements scale accordingly.
| Phase | Typical duration | Key gate |
|---|---|---|
| 01 Discovery & fitment | 2-4 weeks | RFP-coverage matrix signed |
| 02 Solution design | 3-6 weeks | Target architecture sign-off |
| 03 Configuration & integration | 6-12 weeks | Non-prod end-to-end test passes |
| 04 Migration & validation | 4-8 weeks | Reconciliation tie-out for 5 business days |
| 05 Pilot & parallel run | 4-8 weeks | Steering committee go-live decision |
| 06 Production rollout | 2-4 weeks + 30-60 day hypercare | SLA activation, hypercare exit |
Frequently asked questions
The questions lenders ask us before committing to a migration timeline.
How long does an LMS migration actually take?
On the durations above, roughly five to eight months from discovery to hypercare exit for a single-product book, longer where there are many products, partners or co-lending arrangements. The variable that moves the timeline most is rarely the software: it is how quickly the lender can answer questions about its own data and reach decisions on exceptions.
What is a parallel run, and can we skip it?
A parallel run means both systems process the same book for a period and you reconcile them daily until they agree. You can skip it. What you are then doing is moving the discovery of every arithmetic and configuration discrepancy from a controlled window into your live book, where the people who find them are your borrowers.
What happens if reconciliation does not tie out?
The gate does not pass, and that is the point of having one. Every break gets traced to a cause: a configuration difference, a rounding or day-count difference, or genuinely bad source data. The first two are fixed; the third is a decision the lender has to make and record. Five clean business days is the bar, not five approximate ones.
Who does the work, us or the vendor?
Both, and the split should be explicit before phase 01 closes. Vendors own configuration, migration tooling and the reconciliation harness. Lenders own data questions, exception decisions, UAT sign-off and the go / no-go call. Migrations slip most often where this was left implicit and both sides assumed the other held a task.
Can we migrate a live book without downtime?
Effectively yes, but not by avoiding a cutover. The pattern is a parallel run followed by a short freeze window, usually a weekend, in which the final delta is migrated and reconciled before the new system takes writes. Anyone promising a zero-freeze cutover on a live loan book is either running a very small book or has not finished thinking about reversals.
