+# Dashboard migrations
+
+This document describes the Grafana dashboard migration system, including metrics, logging, and testing infrastructure for dashboard schema migrations and API version conversions.
+
+## Overview
+
+## Metrics
+
+The dashboard migration system now provides comprehensive observability through:
+- **Prometheus metrics** for tracking conversion success/failure rates and performance
+- **Structured logging** for debugging and monitoring conversion operations
+- **Automatic instrumentation** via wrapper functions that eliminate code duplication
+- **Error classification** to distinguish between different types of migration failures
+
+### 1. Dashboard conversion success metric
+
+**Metric Name:** `grafana_dashboard_migration_conversion_success_total`
+
+**Type:** Counter
+
+**Description:** Total number of successful dashboard conversions
+
+**Labels:**
+- `source_version_api` - Source API version (e.g., "dashboard.grafana.app/v0alpha1")
+- `target_version_api` - Target API version (e.g., "dashboard.grafana.app/v1beta1")
+- `source_schema_version` - Source schema version (e.g., "16") - only for v0/v1 dashboards
+- `target_schema_version` - Target schema version (e.g., "41") - only for v0/v1 dashboards
+
+**Example:**
+```prometheus
+grafana_dashboard_migration_conversion_success_total{
+  source_version_api="dashboard.grafana.app/v0alpha1",
+  target_version_api="dashboard.grafana.app/v1beta1",
+  source_schema_version="16",
+  target_schema_version="41"
+} 1250
+```
+
+### 2. Dashboard conversion failure metric
+
+**Metric Name:** `grafana_dashboard_migration_conversion_failure_total`
+
+**Type:** Counter
+
+**Description:** Total number of failed dashboard conversions
+
+**Labels:**
+- `source_version_api` - Source API version
+- `target_version_api` - Target API version  
+- `source_schema_version` - Source schema version (only for v0/v1 dashboards)
+- `target_schema_version` - Target schema version (only for v0/v1 dashboards)
+- `error_type` - Classification of the error (see Error Types section)
+
+**Example:**
+```prometheus
+grafana_dashboard_migration_conversion_failure_total{
+  source_version_api="dashboard.grafana.app/v0alpha1",
+  target_version_api="dashboard.grafana.app/v1beta1",
+  source_schema_version="14",
+  target_schema_version="41",
+  error_type="schema_version_migration_error"
+} 42
+```
+
+## Error types
+
+The `error_type` label classifies failures into three categories:
+
+### 1. `conversion_error`
+- General conversion failures not related to schema migration
+- API-level conversion issues
+- Programming errors in conversion functions
+
+### 2. `schema_version_migration_error`
+- Failures during individual schema version migrations (v14→v15, v15→v16, etc.)
+- Schema-specific transformation errors
+- Data format incompatibilities
+
+### 3. `schema_minimum_version_error`
+- Dashboards with schema versions below the minimum supported version (< v13)
+- These are logged as warnings rather than errors
+- Indicates dashboards that cannot be migrated automatically
+
+## Logging
+
+### Log structure
+
+All migration logs use structured logging with consistent field names:
+
+**Base Fields (always present):**
+- `sourceVersionAPI` - Source API version
+- `targetVersionAPI` - Target API version
+- `dashboardUID` - Unique identifier of the dashboard being converted
+
+**Schema Version Fields (v0/v1 dashboards only):**
+- `sourceSchemaVersion` - Source schema version number
+- `targetSchemaVersion` - Target schema version number
+- `erroredSchemaVersionFunc` - Name of the schema migration function that failed (on error)
+
+**Error Fields (failures only):**
+- `errorType` - Same classification as metrics error_type label
+- `erroredConversionFunc` - Name of the conversion function that failed
+- `error` - The actual error message
+
+### Log levels
+
+#### Success (DEBUG level)
+```json
+{
+  "level": "debug",
+  "msg": "Dashboard conversion succeeded",
+  "sourceVersionAPI": "dashboard.grafana.app/v0alpha1",
+  "targetVersionAPI": "dashboard.grafana.app/v1beta1",
+  "dashboardUID": "abc123",
+  "sourceSchemaVersion": 16,
+  "targetSchemaVersion": 41
+}
+```
+
+#### Conversion/Migration Error (ERROR level)
+```json
+{
+  "level": "error", 
+  "msg": "Dashboard conversion failed",
+  "sourceVersionAPI": "dashboard.grafana.app/v0alpha1",
+  "targetVersionAPI": "dashboard.grafana.app/v1beta1",
+  "erroredConversionFunc": "Convert_V0_to_V1",
+  "dashboardUID": "abc123",
+  "sourceSchemaVersion": 16,
+  "targetSchemaVersion": 41,
+  "erroredSchemaVersionFunc": "V24",
+  "errorType": "schema_version_migration_error",
+  "error": "migration failed: table panel plugin not found"
+}
+```
+
+#### Minimum Version Error (WARN level)
+```json
+{
+  "level": "warn",
+  "msg": "Dashboard conversion failed", 
+  "sourceVersionAPI": "dashboard.grafana.app/v0alpha1",
+  "targetVersionAPI": "dashboard.grafana.app/v1beta1",
+  "erroredConversionFunc": "Convert_V0_to_V1",
+  "dashboardUID": "def456",
+  "sourceSchemaVersion": 10,
+  "targetSchemaVersion": 41,
+  "erroredSchemaVersionFunc": "",
+  "errorType": "schema_minimum_version_error",
+  "error": "dashboard schema version 10 cannot be migrated"
+}
+```
+
+## Implementation details
+
+### Automatic instrumentation
+
+All dashboard conversions are automatically instrumented via the `withConversionMetrics` wrapper function:
+
+```go
+// All conversion functions are wrapped automatically
+s.AddConversionFunc((*dashv0.Dashboard)(nil), (*dashv1.Dashboard)(nil),
+    withConversionMetrics(dashv0.APIVERSION, dashv1.APIVERSION, func(a, b interface{}, scope conversion.Scope) error {
+        return Convert_V0_to_V1(a.(*dashv0.Dashboard), b.(*dashv1.Dashboard), scope)
+    }))
+```
+
+### Error handling
+
+Custom error types provide structured error information:
+
+```go
+// Schema migration errors
+type MigrationError struct {
+    msg            string
+    targetVersion  int
+    currentVersion int
+    functionName   string
+}
+
+// API conversion errors  
+type ConversionError struct {
+    msg               string
+    functionName      string
+    currentAPIVersion string
+    targetAPIVersion  string
+}
+```
+
+## Registration
+
+### Metrics registration
+
+Metrics must be registered with Prometheus during service initialization:
+
+```go
+import "github.com/grafana/grafana/apps/dashboard/pkg/migration"
+
+// Register metrics with Prometheus
+migration.RegisterMetrics(prometheusRegistry)
+```
+
+### Available metrics
+
+The following metrics are available after registration:
+
+```go
+// Success counter
+migration.MDashboardConversionSuccessTotal
+
+// Failure counter  
+migration.MDashboardConversionFailureTotal
+```
+
+## Conversion matrix
+
+The system supports conversions between all dashboard API versions:
+
+| From ↓ / To → | v0alpha1 | v1beta1 | v2alpha1 | v2beta1 |
+|---------------|----------|---------|----------|---------|
+| **v0alpha1**  | ✓        | ✓       | ✓        | ✓       |
+| **v1beta1**   | ✓        | ✓       | ✓        | ✓       |
+| **v2alpha1**  | ✓        | ✓       | ✓        | ✓       |
+| **v2beta1**   | ✓        | ✓       | ✓        | ✓       |
+
+Each conversion path is automatically instrumented with metrics and logging.
+
+## API versions
+
+The supported dashboard API versions are:
+
+- `dashboard.grafana.app/v0alpha1` - Legacy JSON dashboard format
+- `dashboard.grafana.app/v1beta1` - Migrated JSON dashboard format  
+- `dashboard.grafana.app/v2alpha1` - New structured dashboard format
+- `dashboard.grafana.app/v2beta1` - Enhanced structured dashboard format
+
+## Schema versions
+
+Schema versions (v13-v41) apply only to v0alpha1 and v1beta1 dashboards:
+
+- **Minimum supported version**: v13
+- **Latest version**: v41  
+- **Migration path**: Sequential (v13→v14→v15...→v41)
+
+## Migration testing
+
+The implementation includes comprehensive test coverage:
+
+- **Backend tests**: Go migration tests with metrics validation
+- **Frontend tests**: TypeScript conversion tests  
+- **Integration tests**: End-to-end conversion validation
+- **Metrics tests**: Prometheus counter validation
+
+### Backend migration tests
+
+The backend migration tests validate schema version migrations and API conversions:
+
+- **Schema migration tests**: Test individual schema version upgrades (v14→v15, v15→v16, etc.)
+- **Conversion tests**: Test API version conversions with automatic metrics instrumentation
+- **Test data**: Uses curated test files from `testdata/input/` covering schema versions 14-41
+- **Metrics validation**: Tests verify that conversion metrics are properly recorded
+
+**Test execution:**
+```bash
+# All backend migration tests
+go test ./apps/dashboard/pkg/migration/... -v
+
+# Schema migration tests only
+go test ./apps/dashboard/pkg/migration/ -v
+
+# API conversion tests with metrics
+go test ./apps/dashboard/pkg/migration/conversion/... -v
+```
+
+### Frontend migration comparison tests
+
+The frontend migration comparison tests validate that backend and frontend migration logic produce consistent results:
+
+- **Test methodology**: Compares backend vs frontend migration outputs through DashboardModel integration
+- **Dataset coverage**: Tests run against 42 curated test files spanning schema versions 14-41
+- **Test location**: `public/app/features/dashboard/state/DashboardMigratorToBackend.test.ts`
+- **Test data**: Located in `apps/dashboard/pkg/migration/testdata/input/` and `testdata/output/`
+
+**Test execution:**
+```bash
+# Frontend migration comparison tests
+yarn test DashboardMigratorToBackend.test.ts
+```
+
+**Test approach:**
+- **Frontend path**: `jsonInput → DashboardModel → DashboardMigrator → getSaveModelClone()`
+- **Backend path**: `jsonInput → Backend Migration → backendOutput → DashboardModel → getSaveModelClone()`
+- **Comparison**: Direct comparison of final migrated states from both paths
