Home Nautilus Safe, Zero-downtime Migrations

Safe, Zero-downtime Migrations

Nautilus supports input from multiple processors simultaneously and can map cards across them (“multicard”). This makes processor migration a non-disruptive operation: Nautilus connects to the core system without interrupting existing processes. The built-in test engine and transaction simulator ensure every integration is validated before production, while multicard capability simplifies reconciliation of data across processors. Because Nautilus adapts to the core rather than the other way around, the process requires only minimal participation from the bank’s technical team.

Non-disruptive

Migrations with Nautilus are planned and executed in clearly defined phases, ensuring a smooth and predictable process. The connection with the old processor is never severed; instead, Nautilus is introduced as an additional transaction source, eliminating downtime. Its multicard capability maps old and new processor cards into a single card record for the core, simplifying reconciliation and making the transition seamless for both operations and customers.

Zero-risk

From the start of migration, Nautilus’s transaction simulator and test engine are used to test the connection with the core system. Test data can be generated across many currenciesstrong> and merchant locations, exposing a wide range of scenarios before production. This thorough validation ensures that potential issues are identified and resolved early, removing risks from the migration process.

Non-intrusive

Because Nautilus adapts its output to the core’s input, changes on the issuer’s side are minimal. The issuer’s technical team is only lightly involved, reducing internal workload and avoiding disruptions to ongoing projects. This design makes the migration process smooth and unobtrusive.

Phased & Controlled

The migration is executed in carefully planned phases, avoiding any “big bang” cutover. The existing processor connection remains intact, while Nautilus is introduced in parallel as an additional transaction source. This step-by-step approach ensures continuity of operations and allows reconciliation to be managed smoothly, including the use of multicard mapping to unify old and new cards into a single view for the core system.
