Overview
Migrating to TuskLang provides enhanced configuration capabilities, better performance, and improved developer experience. This guide covers migration from various configuration systems to TuskLang.
Migration Benefits
// Benefits of migrating to TuskLang
public enum MigrationBenefit {
PERFORMANCE, // Faster parsing and resolution
FLEXIBILITY, // Multiple syntax styles
DATABASE_INTEGRATION, // Direct database queries
SECURITY, // Built-in encryption and validation
MONITORING, // Real-time metrics and monitoring
DEVELOPER_EXPERIENCE // Better tooling and debugging
}Migration Strategies
Choose the appropriate migration strategy based on your application's complexity and requirements.
Phased Migration
public class PhasedMigrationStrategy {
public void executePhasedMigration() {
// Phase 1: Parallel configuration
migrateToParallelConfig();
// Phase 2: Feature migration
migrateFeatures();
// Phase 3: Full migration
completeMigration();
// Phase 4: Optimization
optimizeConfiguration();
}
private void migrateToParallelConfig() {
// Run both old and new configuration systems
PropertiesConfig oldConfig = loadOldConfiguration();
TuskLangConfig newConfig = loadTuskLangConfiguration();
// Validate both produce same results
validateConfigurationEquivalence(oldConfig, newConfig);
}
private void migrateFeatures() {
// Migrate specific features one by one
