# Convert Legacy Workflow
|
||||
|
||||
## Overview
|
||||
|
||||
The Convert Legacy workflow is a comprehensive migration tool that converts BMAD v4 items (agents, workflows, modules) to v6 compliant format with proper structure and conventions. It bridges the gap between legacy BMAD implementations and the modern v6 architecture, ensuring seamless migration while preserving functionality and improving structure.
|
||||
|
||||
## Key Features
|
||||
|
||||
- **Multi-Format Detection** - Automatically identifies v4 agents, workflows, tasks, templates, and modules
|
||||
- **Intelligent Conversion** - Smart mapping from v4 patterns to v6 equivalents with structural improvements
|
||||
- **Sub-Workflow Integration** - Leverages create-agent, create-workflow, and create-module workflows for quality output
|
||||
- **Structure Modernization** - Converts YAML-based agents to XML, templates to workflows, tasks to structured workflows
|
||||
- **Path Normalization** - Updates all references to use proper v6 path conventions
|
||||
- **Validation System** - Comprehensive validation of converted items before finalization
|
||||
- **Migration Reporting** - Detailed conversion reports with locations and manual adjustment notes
|
||||
|
||||
## Usage
|
||||
|
||||
### Basic Invocation
|
||||
|
||||
```bash
|
||||
workflow convert-legacy
|
||||
```
|
||||
|
||||
### With Legacy File Input
|
||||
|
||||
```bash
|
||||
# Convert a specific v4 item
|
||||
workflow convert-legacy --input /path/to/legacy-agent.md
|
||||
```
|
||||
|
||||
### With Legacy Module
|
||||
|
||||
```bash
|
||||
# Convert an entire v4 module structure
|
||||
workflow convert-legacy --input /path/to/legacy-module/
|
||||
```
|
||||
|
||||
### Configuration
|
||||
|
||||
The workflow uses standard BMB configuration:
|
||||
|
||||
- **output_folder**: Where converted items will be placed
|
||||
- **user_name**: Author information for converted items
|
||||
- **conversion_mappings**: v4-to-v6 pattern mappings (optional)
|
||||
|
||||

|
||||
## Workflow Process
|
||||
|
||||
### Phase 1: Legacy Analysis (Steps 1-3)
|
||||
|
||||
**Item Identification and Loading**
|
||||
|
||||
- Accepts file path or directory from user
|
||||
- Loads complete file/folder structure for analysis
|
||||
- Automatically detects item type based on content patterns:
|
||||
- **Agents**: Contains `<agent>` or `<prompt>` XML tags
|
||||
- **Workflows**: Contains workflow YAML or instruction patterns
|
||||
- **Modules**: Contains multiple organized agents/workflows
|
||||
- **Tasks**: Contains `<task>` XML tags
|
||||
- **Templates**: Contains YAML-based document generators
|
||||
|
||||
**Legacy Structure Analysis**
|
||||
|
||||
- Parses v4 structure and extracts key components
|
||||
- Maps v4 agent metadata (name, id, title, icon, persona)
|
||||
- Analyzes v4 template sections and elicitation patterns
|
||||
- Identifies task workflows and decision trees
|
||||
- Catalogs dependencies and file references
|
||||
|
||||
**Target Module Selection**
|
||||
|
||||
- Prompts for target module (bmm, bmb, cis, custom)
|
||||
- Determines proper installation paths using v6 conventions
|
||||
- Shows target location for user confirmation
|
||||
- Ensures all paths use `{project-root}/bmad/` format
|
||||
|
||||
### Phase 2: Conversion Strategy (Step 4)
|
||||
|
||||
**Strategy Selection Based on Item Type**
|
||||
|
||||
- **Simple Agents**: Direct XML conversion with metadata mapping
|
||||
- **Complex Agents**: Workflow-assisted creation using create-agent
|
||||
- **Templates**: Template-to-workflow conversion with proper structure
|
||||
- **Tasks**: Task-to-workflow conversion with step mapping
|
||||
- **Modules**: Full module creation using create-module workflow
|
||||
|
||||
**Workflow Type Determination**
|
||||
|
||||
- Analyzes legacy items to determine v6 workflow type:
|
||||
- **Document Workflow**: Generates documents with templates
|
||||
- **Action Workflow**: Performs actions without output documents
|
||||
- **Interactive Workflow**: Guides user interaction sessions
|
||||
- **Meta-Workflow**: Coordinates other workflows
|
||||
|
||||
### Phase 3: Conversion Execution (Steps 5a-5e)
|
||||
|
||||
**Direct Agent Conversion (5a)**
|
||||
|
||||
- Transforms v4 YAML agent format to v6 XML structure
|
||||
- Maps persona blocks (role, style, identity, principles)
|
||||
- Converts commands list to v6 `<cmds>` format
|
||||
- Updates task references to workflow invocations
|
||||
- Normalizes all paths to v6 conventions
|
||||
|
||||
**Workflow-Assisted Creation (5b-5e)**
|
||||
|
||||
- Extracts key information from legacy items
|
||||
- Invokes appropriate sub-workflows:
|
||||
- `create-agent` for complex agent creation
|
||||
- `create-workflow` for template/task conversion
|
||||
- `create-module` for full module migration
|
||||
- Ensures proper v6 structure and conventions
|
||||
|
||||
**Template-to-Workflow Conversion (5c)**
|
||||
|
||||
- Converts YAML template sections to workflow steps
|
||||
- Maps `elicit: true` flags to `<invoke-task halt="true">{project-root}/bmad/core/tasks/adv-elicit.xml</invoke-task>` tags
|
||||
- Transforms conditional sections to flow control
|
||||
- Creates proper template.md from content structure
|
||||
- Integrates v4 create-doc.md task patterns
|
||||
|
||||
**Task-to-Workflow Conversion (5e)**
|
||||
|
||||
- Analyzes task purpose to determine workflow type
|
||||
- Extracts step-by-step instructions to workflow steps
|
||||
- Converts decision trees to flow control tags
|
||||
- Maps 1-9 elicitation menus to v6 elicitation patterns
|
||||
- Preserves execution logic and critical notices
|
||||
|
||||
### Phase 4: Validation and Finalization (Steps 6-8)
|
||||
|
||||
**Comprehensive Validation**
|
||||
|
||||
- Validates XML structure for agents
|
||||
- Checks YAML syntax for workflows
|
||||
- Verifies template variable consistency
|
||||
- Ensures proper file structure and naming
|
||||
|
||||
**Migration Reporting**
|
||||
|
||||
- Generates detailed conversion report
|
||||
- Documents original and new locations
|
||||
- Notes manual adjustments needed
|
||||
- Provides warnings and recommendations
|
||||
|
||||
**Cleanup and Archival**
|
||||
|
||||
- Optional archival of original v4 files
|
||||
- Final location confirmation
|
||||
- Post-conversion instructions and next steps
|
||||
|
||||
