Source-system inventory
Identify operational systems, spreadsheets, interfaces, owners, record types, dependencies, and retention needs.
Treat migration as a controlled business and data transition, with source systems, records, ownership, validation and cutover explicit before anything moves.

Rental organizations evaluating legacy car rental software replacement, system consolidation, or a move from fragmented operational tools.
Assessment-led scopeMigratable data, tooling, responsibilities, sequence, cutover approach, retention, and support depend on the verified source environment and approved implementation plan.
A credible migration plan separates business-critical data from historical clutter and makes every transformation and exception reviewable.
Identify operational systems, spreadsheets, interfaces, owners, record types, dependencies, and retention needs.
Assess completeness, duplication, format, definitions, history, identifiers, and known quality problems.
Define how approved source fields and business concepts map into the target LAREVONT operating model.
Set record counts, samples, balances, exception thresholds, business review, and approval evidence for each migration cycle.
Coordinate freeze points, final extracts, dependencies, fallback decisions, communications, and post-transition checks.
Prepare teams for new definitions, responsibilities, workflows, reports, and ways of resolving data exceptions.
Each migration cycle reduces uncertainty before the production transition is authorized.
Inventory sources, owners, business uses, quality, integrations, history, legal needs, and operating constraints.
Agree target definitions, field transformations, exclusions, exception handling, and acceptance criteria.
Run controlled extracts and loads, reconcile results, review exceptions, and refine the transition plan.
Move the approved scope, complete operational checks, reconcile agreed evidence, and manage remaining exceptions.
Data cannot be approved by technology alone when it drives reservations, fleet, finance, customers, and daily work.
Approve scope, definitions, quality rules, exceptions, retention, reconciliation, and operational acceptance.
Own extracts, transformations, secure transfer, loads, interfaces, logging, failures, and repeatability.
Confirm that migrated records support the target reservation, fleet, payment, reporting, and exception workflows.
Migration readiness is an implementation decision with enterprise governance, not a background import task.
Access, transfer, storage, testing, retention, and disposal expectations are agreed for the migration scope.
Counts, samples, balances, exceptions, and business workflow checks are defined before approval.
Connected systems, identifiers, event timing, ownership, and transition behavior are included in cutover planning.
New definitions, reports, exception handling, training, communications, and support paths are prepared together.
The answer depends on the source systems, data quality, business need, target model, legal or retention requirements, and available migration tooling. LAREVONT confirms the approved record types, history, transformations, and exclusions after assessment.
There is no responsible universal timeline. Duration depends on source count, volume, quality, complexity, history, integrations, reconciliation requirements, decision speed, rehearsal cycles, and operating constraints.
LAREVONT does not make an unsupported universal guarantee. The project defines cutover, freeze, fallback, reconciliation, exception, and support controls appropriate to the verified environment and agreed risk tolerance.
Not necessarily. LAREVONT is modular and API-first, so a target operating model can retain approved external systems. The migration and integration plan should make ownership and transition boundaries explicit.
