Core & Cloud Modernization
Modernize the core. Move to cloud. Keep the institution running.
ACM moves credit unions, community and mid-sized banks off aging core stacks and onto a cloud-native, regulated-first platform — in phases, without a high-risk rip-and-replace.
Legacy cores were not built for this decade
Most banking technology in production today was architected before real-time payments, mobile-first members, tokenized assets, and post-quantum risk. The result is high run-cost, slow change, and brittle integrations.
Replacing a core is widely seen as one of the riskiest projects an institution can take on. The fear is justified: long timelines, frozen roadmaps, and the chance of a failed cutover. So most teams defer, and the cost of carrying old infrastructure compounds every year.
ACM exists to make core banking modernization a controlled, reversible, phased program — not a single dramatic switch. You keep serving members while the platform underneath changes.
A phased path off the legacy stack
We sit a modern, cloud-native layer alongside your existing core, migrate capability by capability, and decommission the old stack only when the new one has proven itself in production.
1. Assess & map
We map your current core, integrations, data model, and regulatory obligations, then define a migration sequence ordered by risk and value.
2. Stand up the cloud core
A cloud-native banking core is provisioned in parallel — deposits, lending, payments, and ledger — running next to your incumbent system, not on top of it.
3. Migrate in slices
Products and account segments move in measured slices. Each slice is validated, reconciled, and reversible before the next one begins.
4. Run & decommission
Once a workload is proven on the new core, the legacy equivalent is retired. You shed maintenance load and licensing as you go, not all at the end.
A cloud-native, client-owned platform
Cloud banking migration with ACM is not a hosted copy of an old system. It is a complete, brandable banking ecosystem you own and control — a fit for credit unions and community and mid-sized banks alike.
- Cloud-native core: elastic infrastructure that scales with demand instead of fixed, over-provisioned hardware.
- White-label and client-owned: the platform carries your brand, and the institution owns its stack and data — non-custodial options included.
- Real-time by default: real-time ledger, payments, and multi-currency FX across 200+ markets built into the core rather than bolted on.
- Post-quantum cryptography: long-lived financial records are protected against "harvest now, decrypt later" exposure from day one.
- Future-ready rails: RWA tokenization and stablecoin settlement are native to the platform, so you can adopt them when your strategy and regulators are ready.
- Compliance-ready foundation: built for regulated institutions and examiner scrutiny, with controls and audit trails designed in, not retrofitted.
Built for speed, governed for risk
Migration timelines are where most core projects fail. Our delivery model is engineered to compress them without cutting corners on controls.
The ACM Agile Speed Framework breaks modernization into short, measurable increments, each with a working outcome, a rollback path, and clear acceptance criteria. Leadership sees progress in production, not just in status reports.
Because the new core runs in parallel with the old one throughout, every step is reversible until you choose to decommission. That is what makes a phased program safer than a single-date cutover.
Coexistence is an engineering plane, not a hope
Running the cloud-native core beside your incumbent is only safe if both systems stay in sync, account by account, throughout the migration. ACM builds that integration layer first, before a single product slice moves.
Core & ledger connectors
Adapters bridge your existing core, general ledger, and payment processors over APIs and standard file feeds, so the new platform reads and writes alongside the old one rather than replacing its interfaces overnight.
KYC, card & rail reuse
Established KYC/AML, card network, and ACH/wire connections keep working during coexistence. You re-point them to the modern core slice by slice instead of re-onboarding every vendor at cutover.
Continuous reconciliation
Balances, postings, and positions are reconciled between systems on a defined cadence, with breaks surfaced for review, so each migrated slice is provably accurate before the legacy equivalent is retired.
Hosting models that satisfy risk and examiners
Where the modernized core runs is a procurement and supervisory question, not just an infrastructure one. ACM supports the deployment posture your board and regulators expect, and you own the resulting stack.
- Cloud, hybrid, or single-tenant: run elastic public cloud, a hybrid split that keeps designated workloads in your environment, or a private single-tenant instance isolated from other institutions.
- Data residency: deployment regions are chosen to keep member and account data within the jurisdictions your obligations require.
- Elastic cost profile: capacity scales to demand instead of fixed, over-provisioned hardware, supporting up to 95% lower infrastructure cost versus legacy core stacks as workloads move.
- Compliance-ready controls: encryption, post-quantum cryptography, and audit trails are designed to support SOC 2, ISO 27001, PCI-DSS, and HIPAA requirements across whichever model you select.
The same architecture underpins every option, so a phased migration can begin in one model and shift as your strategy matures, without re-platforming.

Talk to ACMFrequently asked questions
Do we have to replace our entire core at once?
No. ACM stands up a cloud-native core alongside your existing system and migrates capability by capability. Each slice is validated and reversible, and the legacy stack is decommissioned only after the new platform is proven in production, avoiding a single high-risk cutover.
How does cloud modernization reduce our costs?
A cloud-native foundation replaces fixed, over-provisioned hardware with elastic infrastructure and retires legacy maintenance and licensing as workloads move. ACM targets up to 95% lower infrastructure cost versus legacy core stacks as a platform value proposition, with savings realized progressively across the migration.
Is the modernized platform built for regulated institutions?
Yes. The platform is regulated-first and compliance-ready, with controls, audit trails, and post-quantum cryptography designed in rather than retrofitted, so it is engineered to stand up to examiner scrutiny for credit unions and community and mid-sized banks.
Does modernizing now lock us into tokenized assets or stablecoins?
No. RWA tokenization and stablecoin settlement are native to the platform but optional. You can adopt them when your strategy and regulators are ready, while still gaining the cost and performance benefits of a cloud-native core today.
