Migrating Builds from TFS 2017 to DevOps Server 2022, a few questions...

Take a look at the below for starting with YAML Pipelines in DevOps Server 2022:

1. Where to Create and Store YAML Files

• YAML pipeline files are typically named azure-pipelines.yml (or similar) and stored in the root of your source repository.
• You can create them manually or use the New Pipeline wizard in DevOps Server 2022, which helps scaffold a basic YAML file.
• Once created, the file is committed to source control—this is what makes it versioned and portable.

2. Creating a New YAML Pipeline

• Go to Pipelines → New Pipeline
• Choose your repository (Git or TFVC)
• Select YAML as the pipeline type
• You can either:
• Use an existing YAML file from the repo
• Start from scratch with a blank editor
• Use a template to generate a starter pipeline

3. YAML Syntax Basics

trigger:
  - main

pool:
  vmImage: 'ubuntu-latest'

steps:
  - task: UseDotNet@2
    inputs:
      packageType: 'sdk'
      version: '6.0.x'

  - script: dotnet build
    displayName: 'Build Project'

4. Classic to YAML Transition Strategy

• Recreate your existing Classic pipelines using the same tasks in YAML format.
• Use the Export to YAML option (if available) in Classic pipelines to get a head start.
• Gradually migrate builds while keeping Classic definitions as fallback until you're confident.
