+# Qt6 Migration - LTS Projects and Applications Validation Results
+
+**Date:** 2026-09-25  
+**Validation Scope:** GROUP10 (LTS Projects) and GROUP11 (LTS Applications)  
+**Build Configuration:** BUILD_RTI=ON, BUILD_GRANTLEE=ON, BUILD_ARCGIS=ON  
+
+---
+
+## Executive Summary
+
+✅ **GROUP10 (LTS Projects): VALIDATION COMPLETE - SUCCESS**  
+⚠️ **GROUP11 (LTS Applications): BLOCKED - Pre-existing dependency issues**
+
+---
+
+## GROUP10 - LTS Projects (9 Targets)
+
+### Build Status: ✅ SUCCESS
+
+All 9 LTS Project targets compiled successfully:
+
+| # | Target | Status |
+|---|--------|--------|
+| 1 | ProjectGuezPlugin | ✅ Built |
+| 2 | ProjectQatarMOUTPlugin | ✅ Built |
+| 3 | ProjectQatarPlugin | ✅ Built |
+| 4 | ProjectLegatusPlugin | ✅ Built |
+| 5 | ProjectDemoPlugin | ✅ Built |
+| 6 | ProjectL400P2Plugin | ✅ Built |
+| 7 | ProjectComMasterPlugin | ✅ Built |
+| 8 | ProjectAhtcPlugin | ✅ Built |
+| 9 | ProjectEtsPlugin | ✅ Built |
+
+### Qt6 Migration Verification
+
+- ✅ All CMakeLists.txt files use `Qt6::` namespace (no `Qt5::` references)
+- ✅ MOC generation successful for all project targets
+- ✅ No compilation errors in project-specific code
+- ✅ All targets link against Qt6 libraries correctly
+
+---
+
+## GROUP11 - LTS Applications (3 Targets)
+
+### Build Status: ⚠️ BLOCKED
+
+**Blocking Issue:** Dependency build failure in `svcPdmClient` (Services/ProjectDataManagement)
+
+### Affected Targets
+
+| # | Target | Status | Blocker |
+|---|--------|--------|---------|
+| 1 | OperatorApplication | ⚠️ Blocked | svcPdmClient |
+| 2 | thp_viewer | ⚠️ Blocked | svcPdmClient |
+| 3 | aarApp | ⚠️ Blocked | svcPdmClient |
+
+### Root Cause Analysis
+
+The Applications depend on `svcPdmClient` library, which has pre-existing Qt6 MOC compatibility issues:
+
+**Error Location:** `build4/Lts/Services/ProjectDataManagement/pdm_dtc_impl.h` and `pdm_ftc_impl.h`
+
+**Compilation Errors:**
+```
+error: no type named 'FunctionReplyObject' in namespace 'ProjectDataManagement::Core'
+error: no member named 'qt_static_metacall' in 'ProjectDataManagement::Core::Ftc'
+error: no member named 'qt_metacast' in 'ProjectDataManagement::Core::Ftc'
+error: no member named 'qt_metacall' in 'ProjectDataManagement::Core::Ftc'
+error: member reference base type 'DtcImpl' is not a structure or union
+error: member reference base type 'FtcImpl' is not a structure or union
+```
+
+**Technical Details:**
+- `QMetaObject::activate<void>` calls failing due to incorrect QObject inheritance
+- Missing `Q_OBJECT` macro or QObject base class in generated implementation classes
+- Type resolution issues with `FunctionReplyObject` (may be `FunctionReply` in Qt6)
+- MOC-generated code incompatible with Qt6 API changes
+
+**Scope Note:** These issues exist in the Services layer (ProjectDataManagement), which is outside the scope of LTS Projects and Applications migration.

+
+## Docker Build Script Changes
+
+### File: `new_docker_build.sh`
+
+**Changes Made:**
+1. Added `GROUP10_TARGETS` array (9 LTS Project targets)
+2. Added `GROUP11_TARGETS` array (3 LTS Application targets)
+3. Added `BUILD_GROUP10` and `BUILD_GROUP11` configuration variables
+4. Added CLI argument parsing: `--group10/--no-group10` and `--group11/--no-group11`
+5. Added environment variable exports for Docker container
+6. Fixed unbound variable errors for BUILD_GROUP7-11
+
+**Validation Command:**
+```bash
+cd qt-migration-legatus/qt6-after/qt6-migrated-legatus
+BUILD_RTI=ON BUILD_GRANTLEE=ON BUILD_ARCGIS=ON \
+  ./new_docker_build.sh --group10 --group11
+```
+
+---
+
+## Recommendations
+
+### Immediate Actions
+
+1. ✅ **GROUP10 validation is complete** - LTS Projects are successfully migrated to Qt6
+2. ⚠️ **GROUP11 requires Services layer fixes** - Address svcPdmClient MOC issues before Applications can be validated
+
+### Next Steps for GROUP11
+
+To unblock LTS Applications validation, the following must be resolved:
+
+1. **Fix QObject inheritance in svcPdmClient:**
+   - Verify `DtcImpl` class inherits from `QObject`
+   - Verify `FtcImpl` class inherits from `QObject`
+   - Add `Q_OBJECT` macro where missing
+
+2. **Update MOC-generated code for Qt6:**
+   - Fix `QMetaObject::activate` signature to match Qt6 API
+   - Resolve `FunctionReplyObject` type (check if renamed to `FunctionReply`)
+   - Update `qt_static_metacall`, `qt_metacast`, `qt_metacall` references
+
+3. **Re-run validation:**
+   ```bash
+   BUILD_RTI=ON BUILD_GRANTLEE=ON BUILD_ARCGIS=ON \
+     ./new_docker_build.sh --group10 --group11
+   ```
+

+
+## Technical Notes
+
+### Qt6 Migration Patterns Observed
+
+**Successful Patterns (GROUP10):**
+- Direct `Qt6::Core`, `Qt6::Widgets`, `Qt6::Network` usage
+- Standard MOC generation with Qt6 tools
+- CMake `find_package(Qt6 COMPONENTS ...)` working correctly
+
+**Problematic Patterns (Services Layer):**
+- Generated code from pdm_service.xml may need template updates
+- Custom QObject-derived classes may need inheritance review
+- Signal/slot connections may need syntax updates for Qt6
+
+### Build Configuration
+
+**Valid Build Variants:**
+- Only `ON` variants are valid per migration rules
+- `BUILD_RTI=ON`, `BUILD_GRANTLEE=ON`, `BUILD_ARCGIS=ON`
+
+**Invalid Configurations:**
+- `OFF` variants not tested (not part of migration scope)
+
+---
+
+## Conclusion
+
+**GROUP10 (LTS Projects) validation is COMPLETE and SUCCESSFUL.** All 9 project targets compile and link correctly with Qt6.
+
+**GROUP11 (LTS Applications) validation is BLOCKED** by pre-existing issues in the Services layer (svcPdmClient). These issues are outside the scope of the LTS Projects and Applications migration task and require separate attention to the ProjectDataManagement service code generation templates.
