CMT Format Compatibility - -**Problem:** Existing tooling, pipelines, and documentation use CMT's schema.xml and data.zip formats. - -**Solution:** Maintain full compatibility with CMT formats for drop-in replacement. - ---- - -## Project Structure - -``` -PPDS.Migration/ -β”œβ”€β”€ PPDS.Migration.csproj -β”œβ”€β”€ PPDS.Migration.snk -β”‚ -β”œβ”€β”€ Analysis/ # Schema analysis -β”‚ β”œβ”€β”€ ISchemaAnalyzer.cs # Schema parsing interface -β”‚ β”œβ”€β”€ SchemaAnalyzer.cs # CMT schema.xml parser -β”‚ β”œβ”€β”€ IDependencyGraphBuilder.cs # Dependency analysis interface -β”‚ β”œβ”€β”€ DependencyGraphBuilder.cs # Build entity dependency graph -β”‚ β”œβ”€β”€ CircularReferenceDetector.cs # Find circular dependencies -β”‚ β”œβ”€β”€ IExecutionPlanBuilder.cs # Plan builder interface -β”‚ └── ExecutionPlanBuilder.cs # Create tiered execution plan -β”‚ -β”œβ”€β”€ Export/ # Parallel export -β”‚ β”œβ”€β”€ IExporter.cs # Export interface -β”‚ β”œβ”€β”€ ParallelExporter.cs # Multi-threaded export -β”‚ β”œβ”€β”€ EntityExporter.cs # Single entity export -β”‚ β”œβ”€β”€ IDataPackager.cs # Packaging interface -β”‚ └── DataPackager.cs # Create CMT-compatible ZIP -β”‚ -β”œβ”€β”€ Import/ # Tiered import -β”‚ β”œβ”€β”€ IImporter.cs # Import interface -β”‚ β”œβ”€β”€ TieredImporter.cs # Tier-by-tier import -β”‚ β”œβ”€β”€ EntityImporter.cs # Single entity import -β”‚ β”œβ”€β”€ IDeferredFieldProcessor.cs # Deferred field interface -β”‚ β”œβ”€β”€ DeferredFieldProcessor.cs # Update deferred lookups -β”‚ β”œβ”€β”€ IRelationshipProcessor.cs # M2M interface -β”‚ └── RelationshipProcessor.cs # Associate M2M relationships -β”‚ -β”œβ”€β”€ Models/ # Domain models -β”‚ β”œβ”€β”€ MigrationSchema.cs # Parsed schema representation -β”‚ β”œβ”€β”€ EntitySchema.cs # Entity definition -β”‚ β”œβ”€β”€ FieldSchema.cs # Field definition -β”‚ β”œβ”€β”€ RelationshipSchema.cs # Relationship definition -β”‚ β”œβ”€β”€ DependencyGraph.cs # Entity dependency graph -β”‚ β”œβ”€β”€ DependencyEdge.cs # Dependency relationship -β”‚ β”œβ”€β”€ CircularReference.cs # Circular dependency info -β”‚ β”œβ”€β”€ ExecutionPlan.cs # Import execution plan -β”‚ β”œβ”€β”€ ImportTier.cs # Tier of parallel entities -β”‚ β”œβ”€β”€ DeferredField.cs # Field to update later -β”‚ β”œβ”€β”€ MigrationData.cs # Exported data container -β”‚ └── IdMapping.cs # Oldβ†’New GUID mapping -β”‚ -β”œβ”€β”€ Progress/ # Progress reporting -β”‚ β”œβ”€β”€ IProgressReporter.cs # Reporter interface -β”‚ β”œβ”€β”€ ConsoleProgressReporter.cs # Console output -β”‚ β”œβ”€β”€ JsonProgressReporter.cs # JSON for tool integration -β”‚ └── ProgressEventArgs.cs # Progress event data -β”‚ -β”œβ”€β”€ Formats/ # File format handling -β”‚ β”œβ”€β”€ ICmtSchemaReader.cs # Schema reader interface -β”‚ β”œβ”€β”€ CmtSchemaReader.cs # Read CMT schema.xml -β”‚ β”œβ”€β”€ ICmtDataReader.cs # Data reader interface -β”‚ β”œβ”€β”€ CmtDataReader.cs # Read CMT data.xml from ZIP -β”‚ β”œβ”€β”€ ICmtDataWriter.cs # Data writer interface -β”‚ └── CmtDataWriter.cs # Write CMT-compatible output -β”‚ -└── DependencyInjection/ # DI extensions - β”œβ”€β”€ ServiceCollectionExtensions.cs # AddDataverseMigration() - └── MigrationOptions.cs # Configuration options -``` - ---- - -## Core Interfaces - -### IExporter - -```csharp -namespace PPDS.Migration.Export; - -/// -/// Exports data from Dataverse using parallel operations. -/// -public interface IExporter -{ - /// - /// Exports data based on schema definition. - /// - /// Path to CMT schema.xml - /// Output ZIP file path - /// Export options - /// Progress reporter - /// Cancellation token - Task ExportAsync( - string schemaPath, - string outputPath, - ExportOptions?

add PPDS.Migration library for high-performance data migration MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements prompts 9-16 from the implementation plan: ## PPDS.Migration Library - Parallel export with configurable degree of parallelism - Tiered import with automatic dependency resolution (Tarjan's algorithm) - Circular reference detection with deferred field processing - CMT format compatibility (schema.xml, data.zip) - Progress reporting (Console and JSON formats) - Security-first design: no PII in logs, connection string redaction ## Key Components - Models: MigrationSchema, DependencyGraph, ExecutionPlan, IdMapping - Analysis: DependencyGraphBuilder, ExecutionPlanBuilder - Export: ParallelExporter with FetchXML paging - Import: TieredImporter with bulk operation support - Formats: CMT schema/data readers and writers - Progress: IProgressReporter with Console/JSON implementations ## CLI Integration - Updated PPDS.Migration.Cli to reference PPDS.Migration - Commands ready to use migration library ## Documentation - Updated CHANGELOG.md with PPDS.Migration features - Updated README.md with package info and examples - Added PPDS.Migration package README πŸ€– Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 --- CHANGELOG.md | 10 + PPDS.Sdk.sln | 15 + README.md |
