ColdFusion Code Analyzer: Catching CF 2025 Compatibility Issues Before They Hit Production

The ColdFusion Code Analyzer is a built-in tool in the ColdFusion Administrator that scans your codebase and flags compatibility problems before you upgrade — which matters enormously for ColdFusion 2025, the release with the largest wave of feature removals in recent CF history. You run it from ColdFusion Administrator → Debugging & Logging → Code Analyzer, point it at a code directory, tell it which CF version you’re coming from, and it produces a report classifying issues as No longer supported (these cause errors), Deprecated (still work, but going away), Modified behavior (may act differently), and New. CF 2025 removed many tags and functions (Flash/Flex integration, cftree/cfmenu/cfcalendar/cfmediaplayer and other UI tags, cfclient, the script query/http helper CFCs, CFMX_COMPAT encryption, and more), plus it jumps to JDK 21 and Tomcat 10.1 (Jakarta EE — javax.* becomes jakarta.). Running the Code Analyzer (and, for deeper coverage, Foundeo's commercial Fixinator, which added a CF 2025 compatibility scanner) turns a scary blind upgrade into a planned one. Even without Administrator access, you can run a free local copy of ColdFusion and point the analyzer at your code. This guide shows how.
