The Subtype Migration Snap-in is designed to facilitate the seamless transition of work items (tickets and issues) from one custom schema subtype to another. It efficiently handles large volumes of work items by processing them in batches, transferring custom field values between corresponding fields and maintaining proper workflow stages while preserving data integrity throughout the migration process.

## Features

- **Command-based workflow**

Initiate the migration with `/migrate_subtype` or halt it with `/stop_migration` commands.

- **Field-mapping configuration**

Map multiple custom fields from source to destination subtype, preserving important data during migration.

- **Batch processing**

Handle large volumes of work items efficiently with progress updates throughout the migration.

- **Failure handling and progress tracking**

Track failed items with detailed error reporting and monitor real-time progress information.

- **Stage migration**

Transitions work items to stages in the target subtype workflow as selected by user from dropdown.
