It is to preserve valid tickets, seat assignments, order histories, payments, refunds and staff operations while establishing which system is authoritative at every point. For a business with future events already on sale, migration is an operational change with live customer consequences. It should be designed around those obligations rather than around a convenient software launch date. ## What should be inventoried before a ticketing migration? **Start with a record and dependency inventory covering everything that must continue to work.** Include future and completed events, venues, seating plans, ticket types, holds, allocations, customer profiles, membership entitlements, orders, complimentary tickets, transfers, refunds, vouchers and financial balances. Then map the surrounding systems: payment gateways, merchant accounts, scanners, box-office terminals, CRM, identity services, email delivery, reporting and partner feeds. For each integration, record whether it reads data, writes data or both. An essential distinction is between *historical information* and *live rights*. A past order may need to remain visible for service and finance. An already-sold ticket for next Saturday needs to be recognised by the entry system, even if the booking was originally created elsewhere. ## How do you map and validate ticketing data? **Data mapping translates old fields and states into the destination model while preserving their meaning.** A migrated order is not correct merely because its customer name and amount are present. Build explicit mappings for record identifiers, event times and time zones, seat coordinates, ticket statuses, price bands, taxes, discounts, refunds, ticket-holder details and admission credentials. Define how duplicates and missing fields will be handled. Keep source IDs so errors can be traced back to the previous system. Some providers offer structured data imports with column mapping and validation before records are created. Others require APIs or assisted migration. Whatever the method, test the mapping against difficult records as well as ordinary paid orders. ### What should reconciliation actually check? **Reconciliation should compare counts, values and entitlement states—not only whether the import job reported success.** For example, compare sold-ticket totals by event and price band, total captured and refunded amounts, outstanding payment balances, active membership counts and seat assignments. Investigate every discrepancy that matters to admission or finance. A hypothetical 2,000-seat event with 1,450 valid sold tickets, 50 complimentary admissions and 100 operational holds must not emerge as 1,600 unrestricted sold tickets. The destination should preserve each category's real rights and restrictions, rather than flattening the records to one total. Use sample orders through to ticket display and gate scanning. Check that cancelled and superseded barcodes cannot re-enter and that transferred rights are assigned to the correct current holder. ## What happens to already-sold tickets and memberships? **Previously issued rights need an explicit continuity design: migrate them into the new admission system or preserve a controlled way to validate them against the old one.** Customers should not be required to buy again because the supplier changed. Decide whether original ticket identifiers can be imported, whether new credentials will be issued, and what happens if customers present old PDFs or wallet passes. For reserved seating, confirm that each seat remains associated with exactly the intended order and that seats do not return to public inventory by mistake. Memberships add validity dates, benefit rules and account links. A customer may have admission to future events or access to a presale even though their original payment record stays with the previous supplier. Document how these entitlements are represented and tested. Payment credentials may not be portable in the same way as order data. Card tokens, merchant accounts, refunds and disputed transactions require a separate plan with the relevant payment service and security advisers. ## Should migration be phased or completed in one cutover? **A phased migration often reduces exposure when events, venues or organisations can be separated safely; a single cutover may be necessary when systems share tightly coupled inventory.** Neither is automatically lower risk. A phased approach might place only newly announced events on the destination while existing live events finish on the previous platform. Another might migrate one venue, test operations, then move others. This reduces simultaneous change but creates a period of dual reporting and support. A single cutover can simplify the customer experience but concentrates risk. If old and new systems can both sell the same seats, the architecture must prevent conflicting reservations. Dual-running *views* is simpler than dual-writing authoritative transactions. Choose an explicit source of truth for each record during transition. Avoid leaving staff to guess whether a refund, transfer or seat release belongs in the old or new system. ## What should a cutover and rollback plan contain? **A cutover plan defines the sequence, stop conditions, verification owners and recovery actions before production changes begin.** It should name the person who can pause sales, approve go-live and choose whether to fix forward or roll back. A typical runbook covers final data extraction, import validation, payment and email configuration, domain/routing changes, ticket delivery, admission device synchronisation, smoke-test orders and live monitoring. Include customer-service messaging and an incident channel for operational teams. Rollback is harder after the new system has accepted purchases. Simply pointing the domain back to the old platform could lose new orders or reopen inventory that was sold after the change. AWS's general cutover guidance similarly distinguishes a rollback before new writes from one after new transactions have occurred. For ticketing, define how any new sales, refunds and barcodes would be reconciled before a reverse cutover. Sometimes a controlled 'fix forward' is safer than pretending the migration never happened. ## How should the team test the new platform? **User acceptance testing should reproduce complete workflows performed by real roles.** Finance staff should reconcile payments, box-office teams should sell and exchange tickets, event managers should alter capacities and gate staff should validate valid, cancelled and duplicate credentials. Test failure conditions: payment approval with delayed confirmation, loss of scanner connectivity, duplicated import records, venue staff with restricted permissions, a transferred ticket and an event cancelled after migration. Verify training materials and support escalation as carefully as the screens. A migration is operationally ready when staff can complete these workflows, material exceptions are resolved and designated owners accept the residual risk. ## What should happen after the cutover? **Keep a controlled hypercare period for incident monitoring, reconciliation and rapid correction.** Track order conversion, failed payments, inventory discrepancies, ticket delivery, gate scans and customer contact reasons. Reconcile processor activity and legacy obligations according to a documented schedule. Retire the old platform only when data retention, ongoing disputes, refunds, statutory records and other obligations are addressed. Confirm export delivery and deletion or archival terms with the former provider. A successful migration is measured by **continuity of sales, rights and operations**, not by the number of records imported or whether the new homepage looks better. ## Related explanations #### [How do you test a ticketing platform before migration?](/strategy-selection/how-do-you-test-a-ticketing-platform-before-migration) Strategy & Selection · Migration and implementation #### [Should ticketing platform migrations happen all at once or in stages?](/strategy-selection/should-ticketing-platform-migrations-happen-all-at-once-or-in-stages) Strategy & Selection · Migration and implementation #### [What data should be migrated when changing ticketing platforms?](/strategy-selection/what-data-should-be-migrated-when-changing-ticketing-platforms) Strategy & Selection · Migration and implementation #### [How should you score a ticketing platform RFP?](/strategy-selection/how-should-you-score-a-ticketing-platform-rfp) Strategy & Selection · Choosing a provider [More in Strategy & Selection →](/strategy-selection)
