 # Qt5/C++11 → Qt6/C++17 Migration Status
 
+## Session 026: Lts/Services Qt5:: to Qt6:: Migration Complete (2026-08-24)
+
+### ✅ All Qt5:: CMake References in Lts/Services Migrated to Qt6::
+
+**Scope:**
+- Migrated all 104 CMakeLists.txt files in Lts/Services module
+- 51 submodules processed (AlarmManagement, AreaEffectSimulation, AssetManagement, AudioVideoManagement, etc.)
+- 1244 files changed (4334 insertions, 4701 deletions)
+
+**Qt5:: → Qt6:: Migrations:**
+- Qt5::Core → Qt6::Core
+- Qt5::Gui → Qt6::Gui
+- Qt5::Widgets → Qt6::Widgets
+- Qt5::Network → Qt6::Network
+- Qt5::Svg → Qt6::Svg
+- Qt5::Concurrent → Qt6::Concurrent
+- Qt5::WebSockets → Qt6::WebSockets
+- Qt5::Sql → Qt6::Sql
+- Qt5::Xml → Qt6::Xml
+- Qt5::Test → Qt6::Test
+- Qt5::SerialPort → Qt6::SerialPort
+
+**Verification:**
+```bash
+$ grep -r "Qt5::" qt6-after/qt6-migrated-legatus/Lts/Services/ --include="*.txt" --include="*.cmake"
+# Zero results - all Qt5:: references migrated
+```
+
+**Source Code Analysis:**
+- QTextCodec: 4 occurrences (all Qt6-compatible with QtGui linkage)
+- QRegExp: 7 occurrences (deprecated but functional, deferred)
+- NULL: Multiple occurrences (deferred to cleanup phase)
+- Q_FOREACH: Multiple occurrences (deferred to cleanup phase)
+- Old SIGNAL/SLOT: No blocking instances found
