Core banking migration can modernize an institution or create serious disruption if it is treated as a simple software installation. Avoid these common mistakes.

1. Starting without a migration strategy

Define business outcomes, scope, phases, owners, dependencies, risks, and success metrics before moving data.

2. Ignoring data quality

Do not transfer duplicates, inconsistent balances, or incomplete records. Profile, clean, map, reconcile, and obtain accountable sign-off.

3. Choosing for today’s volume only

Test the platform against projected customers, transactions, products, and markets. Review modularity and performance under realistic loads.

4. Underestimating integrations

Inventory mobile apps, payments, identity, CRM, fraud, reporting, accounting, and partner dependencies. Define API ownership and fallback procedures.

5. Using a big-bang cutover without evidence

Use controlled environments, end-to-end tests, parallel reconciliation, progressive migration, rollback plans, and clear go/no-go criteria.

6. Neglecting customers and employees

Plan communications, training, support, permissions, and operating procedures. Adoption is part of migration success.

7. Treating compliance as a final check

Include auditability, retention, access, reporting, and regulatory requirements throughout the design.
