Australian mutual bank MoveBank has finished a major overhaul of its banking technology, completing an 18-month migration to Constantinople’s cloud-based core banking platform.
The Brisbane-based institution has shifted its full retail portfolio, including roughly 22,000 customers, away from its long-standing Ultradata infrastructure.
This was not simply a back-end software replacement. Customer accounts, lending products, payments and digital banking services have all moved across as part of the project.
MoveBank Leaves Its Legacy Ultradata Core Behind
MoveBank had relied on Australian banking technology provider Ultradata for years, running its banking operations on the Ultracs core system while using Ultracs App 2 for mobile banking.
That setup has now been replaced by Constantinople.
The new platform covers several pieces of MoveBank’s banking operation in one environment, including customer accounts, loan processing, card payments, regulatory compliance and data storage.
For a mutual with around 22,000 customers, it is a significant infrastructure change. Core migrations remain among the messier projects a financial institution can attempt. Customer balances, historical information, product rules and payment services all need to survive the move without turning the transition into a customer problem.
MoveBank’s migration took 18 months.
Constantinople Runs MoveBank’s New Banking Infrastructure on AWS
Constantinople’s platform is hosted on Amazon Web Services, with MoveBank operating inside a private Virtual Private Cloud environment.
The architecture gives the bank a considerably different technology base from the traditional core infrastructure it has now left behind.
There is an AI component too.
Amazon Bedrock is integrated into the platform, giving MoveBank access to natural-language AI models, including models developed by Anthropic.
That detail is worth watching. Banks have spent plenty of time talking about generative AI at the customer-service layer. Putting access to AI services much closer to core banking infrastructure creates a wider range of possibilities, although exactly how aggressively MoveBank uses those capabilities will matter more than simply having them available.
A New MoveBank App Arrives With the Migration
Customers will see some of the technology change directly.
MoveBank has introduced an updated mobile banking experience alongside the core migration, with features including digital onboarding, categorised spending and real-time expense tracking.
The bank had already prepared members for what it called “Moving Day” on August 1, 2026.
MoveBank warned customers of a temporary outage beginning on the evening of July 31 while services were transferred. The new digital banking services were expected to become available the following afternoon.
There were other practical changes tied to the upgrade as well, including new cards for existing Visa customers, additional digital-wallet functionality and new controls around transfer limits.
Constantinople Is Building a Bigger Australian Banking Footprint
MoveBank is not Constantinople’s only financial-sector customer.
The Australian banking technology company also works with Great Southern Bank and fintech company Tyro Payments.
Constantinople itself is relatively young. Former Westpac executives Macgregor Duncan and Dianne Challenor founded the company in 2022, positioning it as an all-in-one technology and operations platform for banks.
The company raised a US$33 million Series A round in 2024 led by Prosus Ventures, with backing from investors including Airtree Ventures and Square Peg Capital.
MoveBank gives Constantinople something particularly useful: a completed full-scale migration rather than another announcement about a transformation project that has only just started.
There is a difference.
Why the MoveBank Constantinople Migration Matters
Legacy core replacement has become an almost permanent item on the banking industry’s technology agenda, yet ripping out an established core remains expensive, disruptive and risky.
That makes completed migrations more interesting than vendor-selection announcements.
MoveBank has moved its existing customer base rather than building a separate digital bank beside its old infrastructure. Its retail products and customers are now operating on the new platform.
The project also bundles core banking modernisation with a refreshed digital experience, cloud infrastructure and access to AI services. Those pieces increasingly arrive together rather than as isolated technology upgrades.
For Constantinople, the migration becomes a live Australian reference case.
For MoveBank, the harder part starts now. A new core can remove old technology constraints, but its value eventually shows up elsewhere: how quickly the bank launches products, how reliably it operates and whether customers actually notice an improvement.
The migration itself is finished. What MoveBank builds on top of it will be more revealing.
