+# SituationMap Qt6 Migration Status
+
+## Summary
+The SituationMap module has been successfully migrated from Qt5 to Qt6 at the **source code level**. All Qt5 API calls have been updated to Qt6 equivalents.
+
+## Completed Changes
+
+### Qt6 API Migrations
+1. **QStringView::slice() → sliced()** - Fixed in 5 files:
+   - Symbology/sidc_codec.cpp
+   - Symbology/sidc_builder.cpp
+   - Symbology/sidc_builder_base.cpp
+   - Symbology/symbol_properties.cpp
+   - SymbologyImpl/symbol_dictionary_impl.cpp
+
+2. **QSortFilterProxyModel filter changes** - Fixed in base_symbol_model.cpp:
+   - beginFilterChange()/endFilterChange() → invalidateFilter() (3 occurrences)
+
+3. **QFuture const-correctness** - Fixed in base_symbol_model.cpp:
+   - Added `mutable` keyword to 3 lambdas capturing QFuture for waitForFinished() calls
+
+### Directory Structure
+All 22 subdirectories from Qt5 have been copied to Qt6:
+- admin_scripts, ArcGISQt5Hack, ElevationMap, EvalApps, FunctionDialog
+- GeometryModel, GraphicalObjects, LayerAggregation, LocalSrv
+- MapImpl, MapObjects, MapObjectsImpl, MathUtils, ModuleTests
+- Portal, README, Resources, Rubberbands, SideBar
+- Symbology, SymbologyGui, Tests, UnitTests, UnitTestsGeoModel, Utils
+
+## Build Status
+
+### Without ArcGIS (BUILD_ARCGIS=OFF)
+✅ Source code compiles successfully
+⚠️ Some unrelated modules (e.g., EEMFakeServer) require Qt6WebSockets which is not installed
+
+### With ArcGIS (BUILD_ARCGIS=ON)
+❌ **Linker errors** - ArcGIS SDK binary incompatibility
+
+## Critical Issue: ArcGIS SDK Compatibility
+
+### Problem
+The ArcGIS Maps SDK for Qt v300.0.0 library (`libEsriRuntimeQt.a`) was built against **Qt 6.8+**, but the system has **Qt 6.2.4** installed.
+
+**Evidence:**
+- ArcGIS SDK template requires: `Qt 6.8.2` minimum (per sdk/ideintegration/ArcGISRuntimeQtTemplate300_0_0/CMakeLists.txt)
+- System Qt version: `6.2.4`
+- Linker errors show undefined Qt6 internal symbols:
+  - `QMetaObject::invokeMethodImpl`
+  - `QFutureInterfaceBase::hasException()`
+  - `QMetaType::registerHelper`
+  - `QtPrivate::QMetaTypeInterfaceWrapper`
+
+### Required Resolution
+To build with ArcGIS support, one of the following is needed:
+
+1. **Upgrade Qt to 6.8+** (recommended)
+   - Install Qt 6.8.2 or later
+   - Rebuild entire project against Qt 6.8+
+
+2. **Obtain Qt 6.2-compatible ArcGIS SDK**
+   - Contact Esri for an ArcGIS SDK build compatible with Qt 6.2.x
+   - Note: ArcGIS SDK v300 may not support Qt 6.2
+
+3. **Disable ArcGIS temporarily**
+   - Build with `-DBUILD_ARCGIS=OFF`
+   - Complete migration of non-ArcGIS code
+   - Re-enable ArcGIS when compatible SDK is available
+
+## Next Steps
+
+1. **Immediate**: Decide on ArcGIS strategy (upgrade Qt, get compatible SDK, or disable)
+2. **If disabling ArcGIS**: Complete migration of remaining 27 plugin files with beginFilterChange()/endFilterChange()
+3. **After ArcGIS resolution**: Run full test suite to validate migration
