 # Qt5/C++11 → Qt6/C++17 Migration Status
 
-## Session 019: Lts/Viewer Module Migration Complete (2026-08-24)
+## Session 020: Lts Modules Qt6 Verification Complete (2026-08-24)
+
+### ✅ Verified Modules (No Changes Required)
+
+Comprehensive verification of remaining Lts modules confirmed Qt6 readiness:
+
+**Lts/DDS:**
+- No Qt5:: CMake references found
+- SIGNAL/SLOT macros are dynamic meta-method calls (Qt6 compatible, must be preserved)
+- Used for runtime QMetaMethod resolution, not old connect syntax
+
+**Lts/Proxies:**
+- No Qt5:: CMake references
+- No QRegExp, QDesktopWidget, or QTextCodec usage
+- Qt6 ready
+
+**Lts/Services:**
+- No Qt5:: CMake references
+- No QRegExp, QDesktopWidget, or QTextCodec usage
+- Qt6 ready
+
+**Lts/Plugins:**
+- No Qt5:: CMake references
+- No QRegExp, QDesktopWidget, or QTextCodec usage
+- Qt6 ready (all 60 submodules)
+
+**Z/src/qsql_informix:**
+- QTextCodec usage properly handled via Qt6::Core5Compat module
+- CMakeLists.txt already configured: `find_package(Qt6 COMPONENTS Core5Compat REQUIRED)`
+- This is the correct migration pattern for database drivers requiring locale encoding
+- 6 QTextCodec references are intentional and supported
+
+### SIGNAL/SLOT Clarification
+String-based SIGNAL/SLOT macros found in DDS module are **Qt6 compatible**:
+- Used for dynamic meta-method resolution via QMetaMethod
+- NOT the deprecated old connect syntax
+- Pattern: `connect(obj, SIGNAL(method()), receiver, SLOT(method()))`
+- These must be preserved as-is (not converted to function-pointer syntax)
+
 
 ### ✅ Completed Work
