ClearVault manages 3 data types including contact inquiries. Helps you organize, track, and share your work in 1 place for teams and solo users.

Can legacy core banking systems be retired?

Yes. Once historical information is migrated into ClearVault's governed Historical Access Layer, the legacy core can typically be retired while authorized users retain read-only access to historical records.

Does ClearVault replace our core banking platform?

No. ClearVault is not a core banking platform. It is a Historical Access Layer that preserves governed access to historical information from retired systems while your current platform handles active operations.

Can customer service retrieve historical statements?

Yes. Authorized users can search, filter, and browse historical statements through a self-service interface without submitting IT requests.

How long does a core banking migration take?

Core banking modernization often spans 12 months or more depending on scope and integration complexity.

Is historical access read-only?

Yes. Historical records remain read-only with Department-Level Access and Activity Logging.

Can applications access historical records through APIs?

Yes. Approved current applications can retrieve governed historical information through secure APIs.

Who controls permissions?

Administrators control Department-Level Access, including which users and departments can access which historical records, exports, and APIs.

What happens during implementation?

ClearVault works with your team to identify legacy systems, extract and transform historical information, validate the data, and launch governed access. The legacy system can then be retired while historical access continues.

Business Challenge

The Problem Before Modernization

A mid-sized bank operates a legacy core banking platform that has supported deposits, loans, and customer accounts for decades. The platform is costly to maintain, difficult to integrate with modern products, and increasingly out of step with customer expectations.

The institution has selected a modern core platform, but historical customer records, transaction history, statements, and loan documentation must remain accessible for customer service, audits, and regulatory requests. The legacy core cannot simply be switched off.

Typical Environment

What The Organization Looks Like

A legacy core banking platform with deposit, lending, and customer information modules.

Departments relying on historical access include Customer Service, Finance, Compliance, Internal Audit, and Lending Operations. Current applications include the new core platform, a customer portal, reporting tools, and analytics.

Authorized APIs

ClearVault separates historical access from operational software. Legacy information is migrated into a governed Historical Access Layer, where authorized users and modern applications retrieve records through search, exports, and secure APIs.

Current applications continue handling active operations. ClearVault preserves read-only access to historical information—without keeping legacy systems online.

One layer. Every retired system. Governed historical access.
