DAST and SAST security scans identified critical vulnerabilities in Bootstrap 3.3.7 and jQuery 1.12.4 across four enterprise automotive portals. Upgrading these frameworks caused widespread UI breakage due to major architectural changes — grid system changes from float to Flexbox, deprecated components, breakpoint changes, and jQuery compatibility issues. All four portals needed to remain visually consistent throughout.

Upgraded Bootstrap from 3.3.7 to 4.6.2 and jQuery from 1.12.4 to 3.x across all four portals via AEM platform. Replaced deprecated Bootstrap components with modern card-based structure. Migrated float-based layouts to Flexbox. Updated forms, navigation, buttons, and utilities to modern standards. Validated UI consistency against reference production portals throughout the upgrade.

Eliminated security vulnerabilities identified by enterprise DAST/SAST scanning. Modernized frontend architecture across all four automotive portals. Improved platform maintainability and reduced technical debt. Enhanced responsive layout consistency for customer-facing portals.
