Prerequisites

Before starting the migration:

  • All changes committed
  • Working directory clean
  • All tests passing
  • Backup created

Migration Steps

Step 1: Prepare for Migration

# Create backup tag
git tag pre-migration-$(date +%Y%m%d)

# Create migration branch
git checkout -b migration/v{from_version}-to-v{to_version}

# Verify pre-migration checks
python migrator.py validate

Step 2: Run Automated Migration

# Dry run first (preview changes)
python migrator.py migrate --from {from_version} --to {to_version} --dry-run

# Apply migration
python migrator.py migrate --from {from_version} --to {to_version}

Step 3: Manual Changes

Step 4: Update Build Configuration

# Update CMakeLists.txt
cmake_minimum_required(VERSION {min_cmake_version})

# Update dependencies if needed
{dependency_updates}

Step 5: Compile and Test

# Clean build
rm -rf build
mkdir build && cd build

# Configure
cmake .. -DCMAKE_BUILD_TYPE=Release

# Build
cmake --build . --config Release

# Run tests
ctest

Step 6: Verify Migration

  • Code compiles without errors
  • All unit tests pass
  • Integration tests pass
  • Audio quality tests pass
  • No performance regression
