Platform migration from ColdFusion to Java

Convert ColdFusion to Java

Move ColdFusion applications onto Java without losing the business rules buried in years of CFML tags, CFCs, and tag-based templates. Spec-first, validated, and governed end to end.

Six reasons to move off ColdFusion

ColdFusion still serves working applications, but the platform risk and licensing cost compound every year.

Licensing cost compounds

Adobe ColdFusion carries per-server licensing that scales with your footprint. Java runs on an open runtime, removing a recurring line item that grows with the estate.

Same functionality, new platform

Migration does not mean rebuilding features. Forge reconstructs what your CFML templates and CFCs actually do into a Living Spec, then generates Java that preserves that behavior.

Talent pool and hiring

ColdFusion expertise is increasingly scarce and concentrated. Java has one of the deepest hiring pools in enterprise software, which lowers key-person risk immediately.

Security and patch cadence

Actively maintained Java frameworks receive the patches, scanners, and audit tooling that aging ColdFusion runtimes no longer get on the same cadence.

Architecture preserved or improved

Keep the structure that works, or restructure deliberately. The Living Spec makes that an explicit decision, not an accident of the rewrite.

See your ForgeScore before you commit

Every import is scored across eight engineering-health dimensions before a Work Order is planned, so you know what you are dealing with up front.

Every ColdFusion-to-Java project on Forge starts the same way: your codebase is imported, scored across eight engineering-health dimensions with ForgeScore, and reconstructed into a Living Spec before a single line of Java is generated. That is what keeps behavior intact and architecture on plan.

What changes when you move to Java

The shift is more than syntax. Paradigms, data access, and runtime assumptions all move, and each one needs an explicit mapping.

01

Language & paradigm

Tag-based CFML templates and CFC components are restructured into idiomatic Java classes and Spring controllers rather than transliterated tag for tag.

02

Data access

cfquery blocks and inline SQL are re-expressed against JDBC and JPA repositories, with parameter binding and type mappings resolved up front instead of at runtime.

03

Runtime & packaging

Applications served by the ColdFusion engine become standard JVM deployables, with session and application scope mapped onto explicit Spring-managed state.

04

Tooling & workflow

ColdFusion Builder and engine-specific tooling give way to standard IDEs, Maven or Gradle builds, automated tests, and CI pipelines.

What Forge actually produces

Every ColdFusion import is scored across 8 engineering-health dimensions, then broken into Build, Migrate, and Decommission work orders. Here is what that looks like for a data-access finding.

ForgeScore finding

Data Weight

54

How data is modeled, moved, and owned. Moderate score: cfquery blocks embed SQL directly inside templates, so data access and presentation must be separated before either can move.

Medium severity finding

Migration work order

Migrate: CustomerService.cfc

Migrate

Re-express the customer service component as a typed Java repository with equivalent query behavior. Includes verification against the original ColdFusion output before this work order is marked complete.

Common challenges

Most ColdFusion migrations fail for the same handful of reasons, and it is rarely the technology itself.

orderForm.cfmmarkup + rulesmixed
business rules
presentation

Logic embedded in templates

Business rules live inside .cfm view templates mixed with presentation markup, so behavior and layout have to be separated before either can move.

Dead & duplicated code

Years of maintenance obscure what is genuinely still in use versus what can be retired, especially across copied template variants.

Implicit typing & scopes

ColdFusion's loose typing and implicit scope resolution rarely map cleanly onto Java's type system without explicit decisions about nullability and precision.
