📋 Migration Process #

1. Preparation Phase #

Backup Everything:

# Create complete backup
cp -r admindek-vanillajs admindek-backup-$(date +%Y%m%d)
 
# Git backup (if using version control)
git branch migration-backup
git add -A
git commit -m "Pre-migration backup"

Document Current State:

# Record current versions
npm list > current-packages.txt
node --version > system-info.txt
git log --oneline -10 > recent-changes.txt
 
# Document customizations
find . -name "*.custom.*" > custom-files.txt

2. Migration Phase #

Follow Version-Specific Guide:

• Review the appropriate migration guide
• Follow steps in exact order
• Test after each major step
• Document any issues encountered

Common Migration Steps:

1. Update package.json dependencies
2. Run npm install to update packages
3. Update configuration files
4. Migrate custom code if needed
5. Update templates and includes
6. Test thoroughly

3. Validation Phase #

Functionality Testing:

# Build and test
npm run build
npm run preview
 
# Check key functionality:
# ✓ All pages load without errors
# ✓ Navigation works correctly
# ✓ Charts and widgets render
# ✓ Forms function properly
# ✓ Mobile responsive behavior
# ✓ Dark/light mode switching

Performance Verification:

# Check bundle sizes
npm run build
du -sh dist/
 
# Compare with previous version
# Ensure performance hasn't degraded

🔧 Common Migration Scenarios #

Customization Preservation #

CSS Customizations:

// Before migration - save your custom styles
// _custom-overrides.scss
.my-custom-component {
  background: #custom-color;
  padding: 2rem;
}
 
// After migration - verify they still work
// May need to update selectors or variables

JavaScript Customizations:

// Document custom JS modifications
// custom-dashboard.js
function myCustomFunction() {
  // Custom functionality
}
 
// After migration - test custom code
// Update API calls if needed

Configuration Updates #

Theme Configuration:

// v2.x configuration (Gulp-based)
const gulp_config = {
  preset: 'theme-1',
  dark_mode: false
}
 
// v3.x configuration (Vite-based) 
const vite_config = {
  preset_theme: 'preset-1',    // Updated naming
  dark_layout: 'false'         // String values
}

File Structure Changes #

⚠️ Common Issues #

Breaking Changes #

Build System Changes:

• Commands changed (gulp → npm run build)

# v2.x supported Node.js 12+
 
# Update if necessary
nvm install 18
nvm use 18

Dependency Conflicts:

# Clear dependency cache
rm -rf node_modules package-lock.json

# If conflicts persist
npm audit fix

Custom Code Migration #

Template Include Syntax:

<!-- v2.x (Gulp file-include) -->
@@include('layouts/header.html', {
  "title": "Dashboard"
})
 
<!-- v3.x (Vite plugin) - Same syntax! -->
@@include('layouts/header.html', {
  "title": "Dashboard"
})

SCSS Import Updates:
