A concise, practical guide and Checklist designed to help teams migrate CFML applications from Adobe ColdFusion to Lucee with confidence. This downloadable PDF compiles a side‑by‑side mapping of tags, functions, admin settings, and common Integration points so you can quickly identify what works as-is, what needs Refactoring, and what alternatives exist in Lucee Server. If you’re planning a ColdFusion-to-Lucee Migration, this matrix reduces uncertainty, speeds up discovery, and prevents avoidable regressions.

What You’ll Get
- A multi-page PDF Compatibility matrix:
- Tag-by-tag Comparison (e.g., cfquery, cfmail, cfdocument, cfhttp, cfthread, cfloop).
- Function mappings (e.g., DateFormat, QueryExecute, SerializeJSON, Image* functions).
- Status per item: Fully Supported, Partially Supported, Deprecated, Not Available, Use Extension.
- Admin settings parity (ColdFusion Administrator vs. Lucee Web/Server Context).
- Notes on Configuration differences (datasources, JVM, mail, caches, logging).
- Implementation notes and short code examples for common refactors.
- A Migration Checklist that aligns with the matrix.
- Optional starter templates:
- Application.cfc snippet optimized for Lucee.
- Sample Tomcat server.xml and rewrite rules (Nginx/IIS/Apache) for Lucee.
- Docker Compose skeleton for Lucee 6 + PostgreSQL/MySQL (if you choose the “bundle” download).
Overview
What the Compatibility matrix Covers
- CFML surface area: tags, functions, built-in scopes, and admin Features.
- Differences across Adobe ColdFusion (CF11–2023) and Lucee (5.4–6.x).
- Guidance on extensions needed for parity (e.g., PDF, Image, S3, Redis, ORM).
- Known behavioral differences (e.g., null support, JSON serialization, timezone handling).
- Migration flags for Security and Performance (e.g., scriptProtect, secure profile, caching).
How the Matrix Is Organized
- Each entry includes:
- ColdFusion feature name.
- Lucee support status and version notes.
- Implementation tips or replacement strategy.
- Links to Lucee docs or extension pages (fields provided so you can add your URLs).
Supported Environments (Quick reference)

- Reduces Migration risk with targeted notes on edge cases and differences.
- Improves Performance outcomes by pointing to Lucee-native Features (caching, JSON handling, Memory tuning).
- Streamlines planning with a prioritized checklist and references for extensions/config.
Use Cases
- Planning a full migration from Adobe ColdFusion to Lucee.
- Scoping a pilot migration for one application or microservice.
- Auditing a codebase for CFML portability and long-term support.
- Building a DevOps pipeline for Lucee with Docker/CommandBox and automated tests.
How to Use the PDF (Step-by-Step)
1) Download and Verify
- Download: REPLACE-WITH-YOUR-DOWNLOAD-URL
- Verify checksum (if provided).
- Open with an up-to-date PDF viewer to ensure code formatting renders correctly.
2) Identify Your Source and Target
- Note your current ColdFusion version (e.g., CF2018 or CF2021).
- Choose target Lucee version (e.g., 6.0.x).
- In the matrix, filter or scan for items marked with your source/target versions.
3) Inventory Your Application
- Generate a quick inventory:
- Search for tags/functions likely to differ: cfdocument, CFPDF, cfimage, CFLDAP, CFEXCHANGE, CFPRINT, WebSocket gateways, ORM/Hibernate, Custom tags.
- Identify libraries and Java integrations (JARs).
- Map each item to the matrix to assess status: Supported, Partial, Needs Extension, Replace.
4) Plan Replacements and Extensions
- For partial or unsupported items:
- Check matrix suggestions (e.g., “Use Lucee PDF Extension,” “Refactor to cfhtmltopdf,” “Replace Exchange with IMAP/Graph API,” “Use S3 Extension”).
- Note any admin-level configurations required (datasources, mail server, caches).
- Record needed environment variables and JVM flags.
5) Configure a Test Lucee Server
- Fast local setup options:
- CommandBox: box server start cfengine=lucee@6
- Docker: use a lucee/lucee:6.x image with your webroot mounted.
- Apply settings:
- Lucee Administrator (Server/Web Context): add datasources, mail server, caches.
- Application.cfc: set this.mappings, this.datasources, session/cookie Security, and null support.
- Confirm timezones, logging, and character encodings match expectations.
6) Run Tests and Iterate
- Exercise pages that use flagged features (from the matrix).
- Replace or polyfill features as directed.
- Use the PDF’s code snippets to adjust common cases (see below).
- Retest until matrix issues are resolved.
Common Refactor Examples
-
CFDocument/CFPDF:
- ColdFusion:
… - Lucee: use the PDF extension or cfhtmltopdf; ensure fonts are installed in the container/OS.
- ColdFusion:
-
CreateObject / CFOBJECT:
- Prefer script: obj = createObject(“java”, “com.example.ClassName”);
- Ensure JARs are on Lucee’s classpath (deploy under WEB-INF/lucee/lib or via server lib).
-
SerializeJSON differences:
- Lucee’s null handling is stricter when “Full Null Support” is enabled; verify structs/arrays for null keys.
-
QueryExecute:
- Works on both; prefer named parameters with QueryExecute(sql, params, options) for safety and portability.
Best practices
Pre-migration Checklist
- Enable full null support only after verifying code paths.
- Lock down session/cookie settings (httponly, secure, samesite).
- Normalize timezones at the JVM and application level.
- Align datasource names and credentials between CF Admin and Lucee Admin.
- Externalize secrets via environment variables.
Performance tuning
- Use EHCache/Redis or Lucee’s caching for templates and objects.
- Consider function/local scope optimizations where hot paths exist.
- Tune JVM memory (-Xms/-Xmx) and GC according to workload.
DevOps Tips
- Pin your Lucee version to avoid unexpected changes.
- Bake Configuration with CFConfig (if using CommandBox) or scripts for Lucee Admin.
- Add health checks and simple smoke tests for critical endpoints.
Sample Compatibility Snapshot (Abbreviated)
| Feature | Status on Lucee | Notes/Action |
|---|---|---|
| cfquery | Fully Supported | Prefer QueryExecute and bind params. |
| cfmail | Fully Supported | Configure mail server in Lucee Admin. |
| CFDOCUMENT/CFPDF | Partial/Extension | Use Lucee PDF extension or cfhtmltopdf; validate fonts. |
| cfimage/Image* | Partial/Extension | Install Image extension; watch memory usage. |
| CFLDAP | Partial | Verify SSL/TLS and attribute mapping. |
| ORM/Hibernate | Partial | Enable ORM in Application.cfc; review HQL differences. |
| WebSocket/Event Gateways | Not Native | Use Undertow/Socket libs or external broker. |
| Admin API | Different | Use Lucee Admin endpoints or CFConfig for Automation. |

FAQ
Is Lucee fully compatible with Adobe ColdFusion?
Lucee supports the vast majority of CFML used in typical applications. Some features differ by design or require extensions (e.g., PDF/Image, certain gateways). The matrix highlights these items with alternatives and workarounds.
Which ColdFusion versions map best to Lucee 6?
Most CF2018 and CF2021 code runs well on Lucee 6 with minor adjustments. CF11/CF2016 projects may need extra Refactoring, especially around Deprecated tags, legacy ORM settings, or older security defaults.
How should I handle PDF and Image processing?
Install Lucee’s PDF and Image extensions, validate fonts and ICC profiles, and test memory usage under load. The matrix includes notes on replacing cfdocument/cfpdf and using cfhtmltopdf equivalents where applicable.
Can I automate admin settings migration?
Yes. Use Lucee Admin exports or CFConfig (with CommandBox) to script datasources, caches, mail, and mappings. The PDF provides field parity notes and recommended properties for reproducible environments.
What about performance differences after migrating?
Lucee often performs equal or better for CFML workloads. Gains come from efficient JSON handling, caching, and modern JVMs. Use the Best practices section to tune memory, caching, and hot code paths.
